Think like it’s 1995; code like it’s 2035 - Grayscale

This is such a great write-up of the workshop I did in Hong Kong!

Jeremy, it was a pleasure to work with you and you are always welcome here in Hong Kong!

If you fancy having this one-day workshop at your company, get in touch.

Dear Developer, The Web Isn’t About You | sonniesedge.co.uk

This is absolutely brilliant!

Forgive my excitement, but this transcript of Charlie’s talk is so, so good—an equal mix of history and practical advice. Once you’ve read it, share it. I want everyone to have the pleasure of reading this inspiring piece!

It is this flirty declarative nature makes HTML so incredibly robust. Just look at this video. It shows me pulling chunks out of the Amazon homepage as I browse it, while the page continues to run.

Let’s just stop and think about that, because we take it for granted. I’m pulling chunks of code out of a running computer application, AND IT IS STILL WORKING.

Just how… INCREDIBLE is that? Can you imagine pulling random chunks of code out of the memory of your iPhone or Windows laptop, and still expecting it to work? Of course not! But with HTML, it’s a given.

Here are Torre’s notes on my talk at An Event Apart Seattle. (She’s been liveblogging all the talks.)

Here are Luke’s notes from the talk I just gave at An Event Apart in Seattle.

Quick Reminder that Details/Summary is the Easiest Way Ever to Make an Accordion | CSS-Tricks

Hells, yeah! Want to make an accordion widget? Use the details element as your starting point and progressively enhance from there.

Nobody Said CSS Is Easy

One thing I gained a stronger awareness of (simply from working with checkboxes) is that it’s important to progressively enhance UI components, so that a fancy custom one is able to fall back to the default browser styles and functionality. This way, a user can still access the UI if JavaScript or CSS fail.

Responsive Components: a Solution to the Container Queries Problem — Philip Walton

Here’s a really smart approach to creating container queries today—it uses ResizeObserver to ensure that listening for size changes is nice and performant.

There’s a demo site you can play around with to see it in action.

While the strategy I outline in this post is production-ready, I see us as being still very much in the early stages of this space. As the web development community starts shifting its component design from viewport or device-oriented to container-oriented, I’m excited to see what possibilities and best practices emerge.

Progressive Web App for FixMyStreet · Issue #1996 · mysociety/fixmystreet

Here’s a Github issue that turned into a good philosophical debate on how to build a progressive web app: should you enhance your existing site or creating a separate URL?

(For the record: I’m in favour of enhancing.)

Stimulus 1.0: A modest JavaScript framework for the HTML you already have

All our applications have server-side rendered HTML at their core, then add sprinkles of JavaScript to make them sparkle.

Yup!—I’m definitely liking the sound of this Stimulus JavaScript framework.

It’s designed to read as a progressive enhancement when you look at the HTML it’s addressing.

The King vs. Pawn Game of UI Design · An A List Apart Article

I love this analogy and I love this approach—starting with the simplest possible thing and building up from there. This article talks about taking that approach for UI design, but it’s pretty much the same thing I talk about for development in Resilient Web Design.

As Shakespeare once didn’t say, progressive enhancement by any other name would smell as sweet.

Robust Client-Side JavaScript – A Developer’s Guide · molily

This is a terrific resource on writing client-side JavaScript without making too many assumptions.

It starts by covering some of the same topics as Resilient Web Design—fault tolerance, Postel’s law, progressive enhancement—but then goes deep, deep, deep into the specifics of applying that to JavaScript.

Webconf.asia - Workshop The Progressive Web

I’m giving a workshop in Hong Kong on February 21st. If you’re in the area, I’d love to see you there. If you know anyone in Hong Kong, please spread the word.

This workshop will teach you how to think in a progressive way. Together we’ll peel back the layers of the web and build upwards, creating experiences that work for everyone. From URL design to Progressive Web Apps, this journey will cover each stage of technological advancement.

Cascading Web Design with Feature Queries ◆ 24 ways

24 Ways is back! Yay! This year’s edition kicks off with a great article by Hui Jing on using @supports:

Chances are, the latest features will not ship across all browsers at the same time. But you know what? That’s perfectly fine. If we accept this as a feature of the web, instead of a bug, we’ve just opened up a lot more web design possibilities.

i is=”the walrus”

In which Brian takes a long winding route through an explanation of why the is attribute for custom elements is dead before he demonstrates the correct way to use web components:

<!-- instead of writing this -->
<input type="radio" is="x-radio">

<!-- you write this -->
<x-radio>
<input type="radio">
</x-radio>

Sadly, none of the showcase examples I’ve seen for web components do this.

Collapsible Sections

The latest edition of Heydon’s Inclusive Components is absolutely fantastic! The pattern itself—toggling sections of content—is quite straightforward, but then there’s a masterclass in how to create a web component that still allows the content to be accessible in older browsers. The key, as ever, is progressive enhancement:

Whether implemented through web components or not, progressive enhancement not only ensures the interface is well-structured and robust. As we’ve seen here, it can also simplify the editorial process. This makes developing the application and its content more inclusive.

Netflix functions without client-side React, and it’s a good thing - JakeArchibald.com

A great bucketload of common sense from Jake:

Rather than copying bad examples from the history of native apps, where everything is delivered in one big lump, we should be doing a little with a little, then getting a little more and doing a little more, repeating until complete. Think about the things users are going to do when they first arrive, and deliver that. Especially consider those most-likely to arrive with empty caches.

And here’s a good way of thinking about that:

I’m a fan of progressive enhancement as it puts you in this mindset. Continually do as much as you can with what you’ve got.

All too often, saying “use the right tool for the job” is interpreted as “don’t use that tool!” but as Jake reminds us, the sign of a really good tool is its ability to adapt instead of demanding rigid usage:

Netflix uses React on the client and server, but they identified that the client-side portion wasn’t needed for the first interaction, so they leaned on what the browser can already do, and deferred client-side React. The story isn’t that they’re abandoning React, it’s that they’re able to defer it on the client until it’s was needed. React folks should be championing this as a feature.

Building a CSS-only image gallery (with fallbacks)

A great step-by-step walkthrough of building a really nice image gallery without any JavaScript.

The end result is really impressive but there’s still the drawback that the browser history will be updated every time you click on an image thumbnail (because the functionality relies on ID attributes referenced via :target). Depending on your use-case, that may or may not be desirable.

Network Information API

It looks like this is landing in Chrome. The navigator.connection.type property will allow us to progressively enhance based on connection type:

A web application that makes use of a service worker to cache resources during installation might have different bundles of assets that it might cache: a list of crucial assets that are cached unconditionally, and a bundle of larger, optional assets that are only cached ahead of time when navigator.connection.type is 'ethernet' or 'wifi'.

There are potential security issues around fingerprinting that are addressed in this document.

Basic grid layout with fallbacks using feature queries

A really nice example of progressive enhancement: creating a layout with inline-block, then flexbox, then Grid.
