Notifications

I’ve written before about how I use apps on my phone:

If I install an app on my phone, the first thing I do is switch off all notifications. That saves battery life and sanity.

The only time my phone is allowed to ask for my attention is for phone calls, SMS, or FaceTime (all rare occurrences). I initiate every other interaction—Twitter, Instagram, Foursquare, the web. My phone is a tool that I control, not the other way around.

To me, this seems like a perfectly sensible thing to do. I was surprised by how others thought it was radical and extreme.

I’m always shocked when I’m out and about with someone who has their phone set up to notify them of any activity—a mention on Twitter, a comment on Instagram, or worst of all, an email. The thought of receiving a notification upon receipt of an email gives me the shivers. Allowing those kinds of notifications would feel like putting shackles on my time and attention. Instead, I think I’m applying an old-school RSS mindset to app usage: pull rather than push.

Don’t get me wrong: I use apps on my phone all the time: Twitter, Instagram, Swarm (though not email, except in direst emergency). Even without enabling notifications, I still have to fight the urge to fiddle with my phone—to check to see if anything interesting is happening. I’d like to think I’m in control of my phone usage, but I’m not sure that’s entirely true. But I do know that my behaviour would be a lot, lot worse if notifications were enabled.

I was a bit horrified when Apple decided to port this notification model to the desktop. There doesn’t seem to be any way of removing the “notification tray” altogether, but I can at least go into System Preferences and make sure that absolutely nothing is allowed to pop up an alert while I’m trying to accomplish some other task.

It’s the same on iOS—you can control notifications from Settings—but there’s an added layer within the apps themselves. If you have notifications disabled, the apps encourage you to enable them. That’s fine …at first. Being told that I could and should enable notifications is a perfectly reasonable part of the onboarding process. But with some apps I’m told that I should enable notifications Every. Single. Time.

Instagram Swarm

Of the apps I use, Instagram and Swarm are the worst offenders (I don’t have Facebook or Snapchat installed so I don’t know whether they’re as pushy). This behaviour seems to have worsened recently. The needling has been dialed up in recent updates to the apps. It doesn’t matter how often I dismiss the dialogue, it reappears the next time I open the app.

Initially I thought this might be a bug. I’ve submitted bug reports to Instagram and Swarm, but I’m starting to think that they see my bug as their feature.

In the grand scheme of things, it’s not a big deal, but I would appreciate some respect for my deliberate choice. It gets pretty wearying over the long haul. To use a completely inappropriate analogy, it’s like a recovering alcoholic constantly having to rebuff “friends” asking if they’re absolutely sure they don’t want a drink.

I don’t think there’s malice at work here. I think it’s just that I’m an edge-case scenario. They’ve thought about the situation where someone doesn’t have notifications enabled, and they’ve come up with a reasonable solution: encourage that person to enable notifications. After all, who wouldn’t want notifications? That question, if it’s asked at all, is only asked rhetorically.

I’m trying to do the healthy thing here (or at least the healthier thing) in being mindful of my app usage. They sure aren’t making it easy.

The model that web browsers use for notifications seems quite sensible in comparison. If you arrive on a site that asks for permission to send you notifications (without even taking you out to dinner first) then you have three options: allow, block, or dismiss. If you choose “block”, that site will never be able to ask that browser for permission to enable notifications. Ever. (Oh, how I wish I could apply that browser functionality to all those sites asking me to sign up for their newsletter!)

That must seem like the stuff of nightmares for growth-hacking disruptive startups looking to make their graphs go up and to the right, but it’s a wonderful example of truly user-centred design. In that situation, the browser truly feels like a user agent.

Words

I like words. I like the way they can be tethered together to produce a satisfying sentence.

Jessica likes words even more than I do (that’s why her website is called “wordridden”). She studied linguistics and she’s a translator by trade—German into English. Have a read of her post about translating Victor Klemperer to get an inkling of how much thought and care she puts into it.

Given the depth of enquiry required for a good translation, I was particularly pleased to read this remark by John Le Carré:

No wonder then that the most conscientious editors of my novels are not those for whom English is their first language, but the foreign translators who bring their relentless eye to the tautological phrase or factual inaccuracy – of which there are far too many. My German translator is particularly infuriating.

That’s from an article called Why we should learn German, but it’s really about why we should strive for clarity in our use of language:

Clear language — lucid, rational language — to a man at war with both truth and reason, is an existential threat. Clear language to such a man is a direct assault on his obfuscations, contradictions and lies. To him, it is the voice of the enemy. To him, it is fake news. Because he knows, if only intuitively, what we know to our cost: that without clear language, there is no standard of truth.

It reminds me of one of my favourite Orwell essays, Politics and the English Language:

Political language — and with variations this is true of all political parties, from Conservatives to Anarchists — is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind.

But however much I agree with Le Carré’s reprise of Orwell’s call for clarity, I was brought up short by this:

Every time I hear a British politician utter the fatal words, “Let me be very clear”, these days I reach for my revolver.

Le Carré’s text was part of a speech given in Berlin, where everyone would get the reference to the infamous Nazi quote—Wenn ich Kultur höre … entsichere ich meinen Browning—and I’m sure it was meant with a sly wink. But words matter.

Words are powerful. Words can be love and comfort — and words can be weapons.

eLife goes live

The World Wide Web was forged in the crucible of science. Tim Berners-Lee was working at CERN, the European Centre for Nuclear Research, a remarkable place where the pursuit of knowledge—rather than the pursuit of profit—is the driving force.

I often wonder whether the web as we know it—an open, decentralised system—could’ve been born anywhere else. These days it’s easy to focus on the success stories of the web in the worlds of commerce and social networking, but I still find there’s something that really “clicks” with the web and the science (Zooniverse being a classic example).

At Clearleft we’ve been lucky enough to work on science-driven projects like the Wellcome Library and the Wellcome Trust. It’s incredibly rewarding to work on projects where the bottom line is measured in knowledge-sharing rather than moolah. So when we were approached by eLife to help them with an upcoming redesign, we jumped at the chance.

We usually help organisations through our expertise in user-centred design, but in this case the design and UX were already in hand. The challenge was in the implementation. The team at eLife knew that they wanted a modular pattern library to keep their front-end components documented and easily reusable. Given Clearleft’s extensive experience with building pattern libraries, this was a match made in heaven (or whatever the scientific non-theistic equivalent of heaven is).

A group of us travelled up from Brighton to Cambridge to kick things off with a workshop. Before diving into code, it was important to set out the aims for the redesign, and figure out how a pattern library could best support those aims.

Right away, I was struck by the great working relationship between design and front-end development within eLife—there was a great collaborative spirit to the endeavour.

Some goals for the redesign soon emerged:

  • Promote the HTML reading experience as a 1st choice for readers.
  • Align the online experience with the eLife visual identity.

That led to some design principles:

  • Focus on content not site furniture.
  • Remove visual clutter and provide no more than the user needs at any stage of the experience.
  • Aid discovery of value added content beyond the manuscript.

Those design principles then informed the front-end development process. Together we came up with a priority of concerns:

  1. Access
  2. Maintainability
  3. Performance
  4. Taking advantage of browser capabilities
  5. Visual appeal

It’s interesting that maintainability was such a high priority that it superseded even performance, but we also proposed a hypothesis at the same time:

Maintainability doesn’t negatively impact performance.

The combination of the design principles and priorities led us to formulate approaches that could be used throughout the project:

  • Progressive enhancement.
  • Small-screen first responsive images.
  • Only add libraries as needed.

Then we dived into the tech stack: build tools, version control approaches, and naming methodologies. BEM was the winner there.

None of those decisions were set in stone, but they really helped to build a solid foundation for the work ahead. Graham camped out in Cambridge for a while, embedding himself in the team there as they began the process of identifying, naming, and building the components.

The work continued after Clearleft’s involvement wrapped up, and I’m happy to say that it all paid off. The new eLife site has just gone live. It’s looking—and performing—beautifully.

What a great combination: the best of the web and the best of science!

eLife is a non-profit organisation inspired by research funders and led by scientists. Our mission is to help scientists accelerate discovery by operating a platform for research communication that encourages and recognises the most responsible behaviours in science.

Open source

Building and maintaining an open-source project is hard work. That observation is about as insightful as noting the religious affiliation of the pope or the scatological habits of woodland bears.

Nolan Lawson wrote a lengthy post describing what it feels like to be an open-source maintainer.

Outside your door stands a line of a few hundred people. They are patiently waiting for you to answer their questions, complaints, pull requests, and feature requests.

You want to help all of them, but for now you’re putting it off. Maybe you had a hard day at work, or you’re tired, or you’re just trying to enjoy a weekend with your family and friends.

But if you go to github.com/notifications, there’s a constant reminder of how many people are waiting

Most of the comments on the post are from people saying “Yup, I hear ya!”

Jan wrote a follow-up post called Sustainable Open Source: The Maintainers Perspective or: How I Learned to Stop Caring and Love Open Source:

Just because there are people with problems in front of your door, that doesn’t mean they are your problems. You can choose to make them yours, but you want to be very careful about what to care about.

There’s also help at hand in the shape of Open Source Guides created by Nadia Eghbal:

A collection of resources for individuals, communities, and companies who want to learn how to run and contribute to an open source project.

I’m sure Mark can relate to all of the tales of toil that come with being an open-source project maintainer. He’s been working flat-out on Fractal, sometimes at work, but often at home too.

Fractal isn’t really a Clearleft project, at least not in the same way that something like Silverback or UX London is. We’re sponsoring Fractal as much as we can, but an open-source project doesn’t really belong to anyone; everyone is free to fork it and take it. But I still want to make sure that Mark and Danielle have time at work to contribute to Fractal. It’s hard to balance that with the bill-paying client work though.

I invited Remy around to chat with them last week. It was really valuable. Mind you, Remy was echoing many of the same observations made in Nolan’s post about how draining this can be.

So nobody here is under any illusions that this open-source lark is to be entered into lightly. It can be a gruelling exercise. But then it can also be very, very rewarding. One kind word from somebody using your software can make your day. I was genuinely pleased as punch when Danish agency Shift sent Mark a gift to thank him for all his hard work on Fractal.

People can be pretty darn great (which I guess is an underlying principle of open source).

Unlabelled search fields

Adam Silver is writing a book on forms—you may be familiar with his previous book on maintainable CSS. In a recent article (that for some reason isn’t on his blog), he looks at markup patterns for search forms and advocates that we should always use a label. I agree. But for some reason, we keep getting handed designs that show unlabelled search forms. And no, a placeholder is not a label.

I had a discussion with Mark about this the other day. The form he was marking up didn’t have a label, but it did have a button with some text that would work as a label:

<input type="search" placeholder="…">
<button type="submit">
Search
</button>

He was wondering if there was a way of using the button’s text as the label. I think there is. Using aria-labelledby like this, the button’s text should be read out before the input field:

<input aria-labelledby="searchtext" type="search" placeholder="…">
<button type="submit" id="searchtext">
Search
</button>

Notice that I say “think” and “should.” It’s one thing to figure out a theoretical solution, but only testing will show whether it actually works.

The W3C’s WAI tutorial on labelling content gives an example that uses aria-label instead:

<input type="text" name="search" aria-label="Search">
<button type="submit">Search</button>

It seems a bit of a shame to me that the label text is duplicated in the button and in the aria-label attribute (and being squirrelled away in an attribute, it runs the risk of metacrap rot). But they know what they’re talking about so there may well be very good reasons to prefer duplicating the value with aria-label rather than pointing to the value with aria-labelledby.

I thought it would be interesting to see how other sites are approaching this pattern—unlabelled search forms are all too common. All the markup examples here have been simplified a bit, removing class attributes and the like…

The BBC’s search form does actually have a label:

<label for="orb-search-q">
Search the BBC
</label>
<input id="orb-search-q" placeholder="Search" type="text">
<button>Search the BBC</button>

But that label is then hidden using CSS:

position: absolute;
height: 1px;
width: 1px;
overflow: hidden;
clip: rect(1px, 1px, 1px, 1px);

That CSS—as pioneered by Snook—ensures that the label is visually hidden but remains accessible to assistive technology. Using something like display: none would hide the label for everyone.

Medium wraps the input (and icon) in a label and then gives the label a title attribute. Like aria-label, a title attribute should be read out by screen readers, but it has the added advantage of also being visible as a tooltip on hover:

<label title="Search Medium">
  <span class="svgIcon"><svg></svg></span>
  <input type="search">
</label>

This is also what Google does on what must be the most visited search form on the web. But the W3C’s WAI tutorial warns against using the title attribute like this:

This approach is generally less reliable and not recommended because some screen readers and assistive technologies do not interpret the title attribute as a replacement for the label element, possibly because the title attribute is often used to provide non-essential information.

Twitter follows the BBC’s pattern of having a label but visually hiding it. They also have some descriptive text for the icon, and that text gets visually hidden too:

<label class="visuallyhidden" for="search-query">Search query</label>
<input id="search-query" placeholder="Search Twitter" type="text">
<span class="search-icon>
  <button type="submit" class="Icon" tabindex="-1">
    <span class="visuallyhidden">Search Twitter</span>
  </button>
</span>

Here’s their CSS for hiding those bits of text—it’s very similar to the BBC’s:

.visuallyhidden {
  border: 0;
  clip: rect(0 0 0 0);
  height: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
}

That’s exactly the CSS recommended in the W3C’s WAI tutorial.

Flickr have gone with the aria-label pattern as recommended in that W3C WAI tutorial:

<input placeholder="Photos, people, or groups" aria-label="Search" type="text">
<input type="submit" value="Search">

Interestingly, neither Twitter or Flickr are using type="search" on the input elements. I’m guessing this is probably because of frustrations with trying to undo the default styles that some browsers apply to input type="search" fields. Seems a shame though.

Instagram also doesn’t use type="search" and makes no attempt to expose any kind of accessible label:

<input type="text" placeholder="Search">
<span class="coreSpriteSearchIcon"></span>

Same with Tumblr:

<input tabindex="1" type="text" name="q" id="search_query" placeholder="Search Tumblr" autocomplete="off" required="required">

…although the search form itself does have role="search" applied to it. Perhaps that helps to mitigate the lack of a clear label?

After that whistle-stop tour of a few of the web’s unlabelled search forms, it looks like the options are:

  • a visually-hidden label element,
  • an aria-label attribute,
  • a title attribute, or
  • associate some text using aria-labelledby.

But that last one needs some testing.

Update: Emil did some testing. Looks like all screen-reader/browser combinations will read the associated text.

Accessible progressive disclosure revisited

I wrote a little while back about making an accessible progressive disclosure pattern. It’s very basic—just a few ARIA properties and a bit of JavaScript sprinkled onto some basic HTML. The HTML contains a button element that toggles the aria-hidden property on a chunk of markup.

Earlier this week I had a chance to hang out with accessibility experts Derek Featherstone and Devon Persing so I took the opportunity to pepper them with questions about this pattern. My main question was “Should I automatically focus the toggled content?”

Derek’s response was very perceptive. He wanted to know why I was using a button. Good question. When you think about it, what I’m doing is pointing from one element to another. On the web, we point with links.

There are no hard’n’fast rules about this kind of thing, but as Derek put it, it helps to think about whether the action involves controlling something (use a button) or taking the user somewhere (use a link). At first glance, the progressive disclosure pattern seems to be about controlling something—toggling the appearance of another element. But if I’m questioning whether to automatically focus that element, then really I’m asking whether I want to take the user to that place in the document—in other words, linking to it.

I decided to update the markup. Here’s what I had before:

<button aria-controls="content">Reveal</button>
<div id="content"></div>

Here’s what I have now:

<a href="#content" aria-controls="content">Reveal</a>
<div id="content"></div>

The logic in the JavaScript remains exactly the same:

  1. Find any elements that have an aria-controls attribute (these were buttons, now they’re links).
  2. Grab the value of that aria-controls attribute (an ID).
  3. Hide the element with that ID by applying aria-hidden="true" and make that element focusable by adding tabindex="-1".
  4. Set aria-expanded="false" on the associated link (this attribute can be a bit confusing—it doesn’t mean that this element is not expanded; it means the element it controls is not expanded).
  5. Listen for click events on those links.
  6. Toggle the aria-hidden and aria-expanded when there’s a click event.
  7. When aria-hidden is set to false on an element (thereby revealing it), focus that element.

You can see it in action on CodePen.

New edition

Six years ago I wrote a book and the brand new plucky upstart A Book Apart published it.

Six years! That’s like a geological age in internet years.

People liked the book. That’s very gratifying. I’m quite proud of it, and it always gives me a warm glow when someone tells me they enjoyed reading it.

Jeffrey asked me a while back about updating the book for a second edition—after all, six years is crazy long time for a web book to be around. I said no, because I just wouldn’t have the time, but mostly because—as the old proverb goes—you can step in the same river twice. Proud as I am of HTML5 For Web Designers, I consider it part of my past.

“What about having someone else update it?” Well, that made me nervous. I feel quite protective of my six year old.

“What about Rachel Andrew?” Ah, well, that’s a different story! Absolutely—if there’s one person I trust to bring the up to date, it’s Rachel.

She’s done a fine, fine job. The second edition of HTML5 For Web Designers is now available.

I know what you’re going to ask: how much difference is there between the two editions? Well, in the introduction to the new edition, I’m very pleased to say that Rachel has written:

I’ve been struck by how much has remained unchanged in that time.

There’s a new section on responsive images. That’s probably the biggest change. The section on video has been expanded to include captioning. There are some updates and tweaks to the semantics of some of the structural elements. So it’s not a completely different book; it’s very much an update rather than a rewrite.

If you don’t have a copy of HTML5 For Web Designers and you’ve been thinking that maybe it’s too out-of-date to bother with, rest assured that it is now bang up to date thanks to Rachel.

Jeffrey has written a lovely new foreword for the second edition:

HTML5 for Web Designers is a book about HTML like Elements of Style is a book about commas. It’s a book founded on solid design principles, and forged at the cutting edge of twenty-first century multi-device design and development.

The travelling time is underway. I’m in Denmark right now, leading an HTML5 workshop at NoMA, the Nordic Multimedia Academy, and thanks to some excellent questions from the students, it’s all going smoothly.

Last week I was in Belgium for the Phare conference, which also went smoothly. I enjoyed giving my presentation and I really enjoyed the excellent hospitality of the Ghentians.

While I was in Belgium, the occasion of my fortieth birthday arrived with a sense of long-foreseen inevitability. I spent it in Bruges.

Four zero. The big four oh. Two squared times ten. The answer to life, the universe and everything minus two.

The photons that were reflected from Earth at the time of my birth are arriving at GJ 1214 b. Or, to put in another way, the light that left GJ 1214 at the moment of my birth is entering our solar system, perhaps even reaching the retinas of human beings somewhere on this planet who happen to be looking into just the right part of the sky at just the right time.
