This week I'm in A Coruña, Galicia, attending the @webengineshackfest.org 👩‍💻 where we are discussing the future of web engines and standards. Given the potential impact on future web development, I thought it would be helpful to share some of my personal notes from the event. ✍️👇

If you have existential feelings about the state of your software stack, just remember that on the web it’s completely undefined which element a mouse click returns.

Evergreen sentiment. (If you always wanted to be a specification editor, wiki.whatwg.org/wiki/Specs/t... has some suggestions. Most still relevant.)

Web component folks: A common feature with request is to "inherit from a button". If that's something you want, which specific button behaviours is it you want to inherit? Why is putting a button in the shadow root not the answer?

I got permission to share this, and I'm extremely grateful for that. The Onion got this letter from one of our subscribers in Alaska. She works with dementia patients and decided to leave a copy in the car for each one. This email made my year. Read it and you'll see what I mean. People are good.

I work as an elder and hospice caregiver, which I am oddly passionate about. I can love on them shamelessly and no one complains about my codependence. It's a win-win situation.

Many of my caregiving colleagues complain about the repetitive questions and, sometimes reactions, of the elderly, especially when those patients happen to read the newspaper, especially with the current downward spiral of our country — as if these people haven't lived through enough horror...

I love my dementia peeps, but sometimes wonder if there's a Guinness Book World Record for how many times an hour a dementia patient can repeat the same question — it's got to be in the hundreds. At least with small children, they ask different questions. Dementia patients will get stuck on one short question and ask it until you can interrupt their train(carousel) of thought and successfully redirect their attention. That carousel is pretty manic sometimes.

A couple days ago, I picked up my mail from the post office and drove over to the nursing home to take (let's call her "Miss Daisy") Miss Daisy out for a drive. Before we took off on our road trip, to the end of The Road and back, in our landlocked little town (Juneau, Alaska), I set my copy of The Onion down in front of her.

Over our two-hour excursion, tiny Miss Daisy read that front page at least a dozen times and each time she would snicker, giggle, and guffaw, then put it down on the dash board and, a minute later, discover it anew. I think it was the best afternoon of my life. We don't often hear them laugh and when they do, it's the sweetest thing you've ever heard.

...

Thank you, thank you, thank you, for the really important work all of you do. You make the world a better place.

If you write code to make websites (HTML, CSS, JS, Web API, Media) and you get frustrated trying to wrangle your code to work in Safari, which bugs are blocking you? Which existing features would you most like to see improved? If you got a chance to order priorities which effort would you put first?

Please don't publish / release a polyfill for unshipped Web features. Someone is bound to use it in production and ruin it for everyone else.

Anne van Kesteren @annevk.nl · 27/02/2025

And yet another polyfill appears to have poisoned the standards well. This time for scoped custom element registries. People never learn. 🫠

I have at times told people that if you want to generate XML, you should use a serializer. So when I had to generate a serialized CSS URL value containing a data: URL of an SVG document of which colors could vary, I immediately went for string manipulation and concatenation. 😅

Almost time to sign off for the year. Web standard proposals to finish in (early?) 2025: - Declarative Web Push - Scoped Custom Element Registries - HTML (and SVG & MathML) Sanitizer API - moveBefore() - fetchLater() - float16 in 2D canvas - <button command> and quite a few more. Happy holidays!

git blame as visualized by GitHub (or Searchfox for the HTML standard) is an amazing development tool for projects that span decades. In particular for projects that enforce good commit messages. Being able to answer why something is the way it is, can be crucial when changing it.

@annevk.nl and I worked on a refined proposal to untie scoped element registry from shadow DOM so that you can use a scoped registry without shadow DOM. Your feedback is appreciated: github.com/whatwg/html/...

https://github.com/WICG/webcomponents/blob/gh-pages/proposals/Scoped-Custom-Element-Registries.md is a good proposal, but it ties the functionality too much to shadow roots. This is Ryosuke and I's...

We implemented a new value for `background-clip` called `border-area`. It lets you use CSS fill a border with a background image or gradient. This article explains how it works, and shows up the possibilities in 7 demos. #css #webdesign #webdevelopment #graphicdesign webkit.org/blog/16214/b...

How’d you like to use CSS to easily create a border from an image or gradient?

The increased URL interoperability between browsers motivated me to do another pass at the remaining open issues. Fully solving file: URLs and URL parsing overall feels within reach for 2025. The IDNA BiDi issue depends on Unicode, but it is scheduled for Unicode 17.0.

This seems like a great idea at first, except that it is very ASCII-compatible-alphabets-centric and ASCII has confusables as well, e.g., l vs I. Passkeys are the answer.

After working on URLs for well over a decade, we finally hit a point where real browser convergence on core aspects is happening. Experimental browser builds are at ~96% (Chromium), ~99% (Gecko), and ~100% (WebKit) in Interop 2024’s URL category. Very exciting to see! Kudos!

If your website does its own video controls, please adopt the :volume-locked pseudo-class to determine whether to offer volume control. Notably iOS and iPadOS manage their volume globally.

Finally had some time to review WHATWG HTML Standard PRs. A lot of exciting technology in the works: <button command commandfor>, ShadowRealm, enforcing noopener for cross-top-level-site blob: URLs, <dialog closedby>, a completely revamped <select> element, and then some.
