We've created a tool called the "Screen reader support look up tables" designed to help people quickly check how screen readers interpret HTML elements and attributes across multiple combinations of browser and screen reader.

A lot has happened since Chrome shipped Same-Document View Transitions in 2023.

In 2024 we shipped Cross-Document VTs, added refinements such as `view-transition-class` and VT Types, and also welcomed Safari in adding VT support.

And this year … well, I wrote a post summing it all up.

Manhattan this morning.
Person crossing the street. We only see a blurry figure as the street is filled with smoke coming from the underground. Traffic lights seen in background. Person walking on sidewalk early morning. Black figure as the light is coming from behind the person, from traffic light. Seagull flying against an orange sun rise sky. The Brooklyn bridge can be seen, out of focus, in the background. Panorama photo of the Brooklyn bridge at sunrise.

Folks who want to see JPEG-XL supported in more browsers, what is it about the format that attracts you to its use on the web?

Right!! Knowing that most slide decks are picture heavy with no text, speaker notes are really important.

I gave a lightning talk at yesterday’s @smashingconf.com Jam session on CSS masonry. Here are my slides.

In short: Masonry isn’t only for Pinterest-style layouts, doing Masonry on the web today is hard, but built-in Masonry support is coming to browsers very soon!

DevTools wish: to be able to easily disable individual items in value lists. For example, one-click disable of a background layer, but not other background layers too.

Based on last year's State of HTML, 60% of web developers find it challenging to keep informed of new web platform features, which I can definitely understand.

At the same time, I keep seeing newsletters and blogs that seem to be doing a great job at it.

What's missing for you?

I have Copilot in VSCode, but I only use as a smarter auto-complete. I've never used it to generate entire scripts or css or html, and I wouldn't trust it to do so.
But as an autocomplete/intellisense, it's really good because it gets your context way better than normal autocomplete.

James and Simon talked me through how WPT works, the integration challenges and how much work the older test suites were; @patrickbrosset.com reminded me of how Microsoft and Google helped jumpstart test262 and @foolip.org explained how much WPT changed Chromium culture when Google joined in too
How a Shared Test Suite Fixed the Web’s Biggest Problems
The story of Web Platform Tests (WPT), the collaborative test suite that transformed the web from an inconsistent platform into a stable one.

Oh and, @smashingconf.com is a really cool conference by the way. The team is awesome, and the speaker line-up for next week is incredible.

Microsoft Edge is super happy to be a partner once again.

Check it out: smashingconf.com/ny-2025

Did you know that AVIF (the AV1 Image File Format) was supported in all the major browsers (Firefox, Safari, Chrome/Edge)?
This has been the case for almost 2 years at this point.

@tunetheweb.com MDN says that the first-paint and first-contentful-paint entries of the PerformancePaintAPI aren't supported on Chromium unless you set the soft navigation flag.
It's weird because patrickbrosset.com/lab/paint-pe... seems to work in Chrome/Edge without a flag.
Is MDN out of date?

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?

So much for a soft launch…the cat's out of the bag. I just hope it doesn't get my mascot. 😅

📢 The Interop 2026 proposal window is closing later today!

122 proposals have been created: github.com/web-platform...

Is anything missing from that list? Are there critical building blocks of the web which you need to work the same in all browsers?

If so, add it, or vote for it with a 👍!

Welcome to another episode of unreadable but very fun fonts. Let me introduce you to Swiss Cheese Mono.
The perfect font, for people who tend to send "cheese" instead of "cheers" at the end of their emails.
