The amazing power of service workers | Go Make Things

So, why would you want to use a service worker? Here are some cool things you can do with it.

Chris lists some of the ways a service worker can enhance user experience.

Lateral Thinking With Withered Technology · Matthias Ott – User Experience Designer

What web development can learn from the Nintendo Game and Watch.

The Web now consists of an ever-growing number of different frameworks, methodologies, screen sizes, devices, browsers, and connection speeds. “Lateral thinking with withered technology” – progressively enhanced – might actually be an ideal philosophy for building accessible, performant, resilient, and original experiences for a wide audience of users on the Web.

Is my host fast yet?

This is an interesting project to try to rank web hosts by performance:

Real-world server response (Time to First Byte) latencies, as experienced by real-world users navigating the web.

Progressive · Matthias Ott – User Experience Designer

Progressive enhancement is not yet another technology or passing fad. It is a lasting strategy, a principle, to deal with complexity because it lets you build inclusive, resilient experiences that work across different contexts and that will continue to work, once the next fancy JavaScript framework enters the scene – and vanishes again.

But why don’t more people practice progressive enhancement? Is it only because they don’t know better? This might, in fact, be the primary reason. On top of that, especially many JavaScript developers seem to believe that it is not possible or necessary to build modern websites and applications that way.

A heartfelt look at progressive enhancement:

Some look at progressive enhancement like a thing from the past of which the old guard just can’t let go. But to me, progressive enhancement is the future of the Web. It is the basis for building resilient, performant, interoperable, secure, usable, accessible, and thus inclusive experiences. Not only for the Web of today but for the ever-growing complexity of an ever-changing and ever-evolving Web.

This is great! Ideas for allowing more styling of form controls. I agree with the goals 100% and I like the look of the proposed solutions too.

The team behind this are looking for feedback so be sure to share your thoughts (I’ll probably formulate mine into a blog post).

An Introduction To Stimulus.js — Smashing Magazine

An intro to Stimulus, the lightweight JavaScript library from Basecamp that takes a progressive enhancement approach, as seen with HEY.

One aspect I really like about the approach Stimulus encourages, is I can focus on sending HTML down the wire to my users, which is then jazzed up a little with JavaScript.

I’ve always been a fan of using the first few milliseconds of a user’s attention getting what I have to share with them — in front of them. Then worrying setting up the interaction layer while the user can start processing what they’re seeing.

Furthermore, if the JavaScript were to fail for whatever reason, the user can still see the content and interact with it without JavaScript.

Quotebacks and hypertexts (Interconnected)

What I love about the web is that it’s a hypertext. (Though in recent years it has mostly been used as a janky app delivery platform.)

I am very much enjoying Matt’s thoughts on linking, quoting, transclusion, and associative trails.

My blog is my laboratory workbench where I go through the ideas and paragraphs I’ve picked up along my way, and I twist them and turn them and I see if they fit together. I do that by narrating my way between them. And if they do fit, I try to add another piece, and then another. Writing a post is a process of experimental construction.

And then I follow the trail, and see where it takes me.

HTML Tutorial for Beginners 101 (Including HTML5 Tags) - WebsiteSetup

A really great one-page guide to HTML from Bruce. I like his performance-focused intro:

If your site is based on good HTML, it will load fast. Browsers incrementally render HTML—that is, they will display a partially downloaded web page to the user while the browser awaits the remaining files from the server.

Modern fashionable development techniques, such as React, require a lot of JavaScript to be sent to the user. When it’s all downloaded, the user’s device must parse and execute the JavaScript before it can even start to construct the page. On a slow network, or on a cheaper, low-powered device, this can result in an excruciatingly slow load and is a heavy drain on the battery.

Hybrid positioning with CSS variables and max() – Lea Verou

Yet another clever technique from Lea. But I’m also bookmarking this one because of something she points out about custom properties:

The browser doesn’t know if your property value is valid until the variable is resolved, and by then it has already processed the cascade and has thrown away any potential fallbacks.

That explains an issue I was seeing recently! I couldn’t understand why an older browser wasn’t getting the fallback I had declared earlier in the CSS. Turns out that custom properties mess with that expectation.

CUBE CSS - Piccalilli

I really, really like Andy’s approach here:

The focus of the methodology is utilising the power of CSS and the web platform as a whole, with some added controls and structures that help to keep things a bit more maintainable and predictable. The end-goal is shipping as little CSS as possible—leaning heavily into progressive enhancement and modern techniques.

If you use the cascade for everything, you’re going to run into trouble. But equally, micro-managing styles on every element will also get you into trouble. I think Andy’s found a really great sweet spot here that gets the balance just right.

CUBE CSS in essence, is a progressive enhancement approach, vs a fight against the grain of CSS or a pixel-pushing your project to within an inch of its life approach.

Yes! It feels very “webby” to me.

Designing for Progressive Disclosure by Steven Hoober

Progressive disclosure interface patterns categorised and evaluated:

  • popups,
  • drawers,
  • mouseover popups (just say no!),
  • accordions,
  • tabs,
  • new pages,
  • scrolling,
  • scrolling sideways.

I really like the hypertext history invoked in this article.

The piece finishes with a great note on the MacNamara fallacy:

Everyone thinks metrics let us measure results. But, actually, they don’t. They measure only what they are measuring. Engagement, for example, is not something that can be measured, so we use an analogue for it. Time on page. Or clicks.

We often end up measuring what is quick, cheap, and easy to measure. Therefore, few organizations regularly conduct usability testing or customer-satisfaction surveys, but lots use analytics.

Even today, organizations often use clicks as a measure of engagement. So, all too often, they design user interfaces to generate clicks, so the system can measure them.

The beauty of progressive enhancement - Manuel Matuzović

Progressive Enhancement allows us to use the latest and greatest features HTML, CSS and JavaScript offer us, by providing a basic, but robust foundation for all.

Some great practical examples of progressive enhancement on one website:

  • using grid layout in CSS,
  • using type="module" to enhance a form with JavaScript,
  • using the picture element to provide webp images in HTML.

All of those enhancements work great in modern browsers, but the underlying functionality is still available to a browser like Opera Mini on a feature phone.

This isn’t the time to get precious about your favourite design and development tools. Use progressive enhancement as your philosophy. Your service might have to be accessed on old devices in hospitals with outdated tech or unsupported operating systems. HTML+CSS is your best bet to ensure that the service can be accessed in unlikely scenarios you’ve never even considered. Do you want to take that risk at a time like this? Nope, me neither.

Save the React squabbles for another time. Make it accessible and robust from day one.

Interactive Elements: A Strange Game

Just today I was discussing with Trys and Cassie why developers tend to create bespoke JavaScript-driven components rather than using the elements that browsers give us for free. It all comes down to the ability to style the user interface.

Here, Brian proposes a kind of minimum viable web component that handles logic like keyboard control and accessibility, but leaves the styling practically untouched. Check out his panel-set demo of a tabbed interface.

I really, really like the way that it wraps existing content. If the web component fails for any reason, the content is still available. So the web component is a progressive enhancement:

An experimental custom element that wraps plain-old HTML (view the source) and decorates function, keyboard handling, accessibility information.

Web Typography News #43: Typesetting Moby-Dick, part 2

Great typography on the web should be designed in layers. The web is an imperfect medium, consumed by countless different devices over untold numbers of network connections—each with their own capabilities, limitations, and peculiarities. To think that you can create one solution that will look and work the same everywhere is a fantasy. To make this more than just one nice book website, the whole project and process needs to embrace this reality.

What is a resilient website? (with Jeremy Keith) | A Question of Code

I really enjoyed having a chat with Ed and Tom on their podcast. It’s aimed at people making a career shift into web development, but that didn’t stop me banging on about my usual hobby horses: progressive enhancement, resilient web design, and all that jazz.
