With highly profitable companies using AI to clean room reimplement existing projects, it’s more important than ever to support independent nonprofit open source projects like ESLint. We’ve been doing the work for 13 years. eslint.org/donate

Oh hey I finally got one

Correction: since this video was recorded, MWG has been updated to improve cross-browser compatibility. allow-discrete shouldn't be used in the transition shorthand; set it separately in transition-behavior so older browsers don't drop the whole transition.

The `unload` event no longer fires in Chrome by default! Since the advent of the mobile web this has become increasingly unreliable and we think that's a footgun for devs who might think it works. We've spent the last 3 years carefully removing it from Chrome. developer.chrome.com/blog/unload-...

Side-by-side test for building dialogs: standard agent vs. agent with Modern Web Guidance 🏁 Both generate similar UIs, but the guided version skips four separate event listeners in favor of `commandfor` and `command` attributes, with less code overall → goo.gle/mwg

I'm really glad we're running this again. It helped us prioritise a lot of work this year. The previous method was 👍 on GitHub issues, which (imo) is too easily gamed, either intentionally or unintentionally.

Link Parameters is the thing that gives you the ability to style embedded external SVGs. Something many have wanted to do for a long time! If you want to show your support of this, give these 2 issues a thumbs-up and comment: 💬 github.com/web-platform... 💬 github.com/web-platform...

Building dynamic touch gestures like swipe-to-remove often causes coding agents to generate overly complex JavaScript, leading to janky animations. Modern Web Guidance solves this by providing your agent with structured, up-to-date implementation guides → goo.gle/mwg

I was going to do a short post on Modern Web Guidance; it turned into a huge deep dive. Here's what it does, why it raised eyebrows, and on-point information with truth bombs. I tried to be complete and honest. It's not magic, but in time, it might just make the web a little bit better.

CSS sibling-count() and sibling-index() are newly available across engines! Here's how they work:

Great news! The CSS sibling-count() and sibling-index() functions are now Baseline Newly Available! I.e implemented in all major browsers.

Skip writing complex JavaScript to make form elements like textarea fit user input 🍝 The field-sizing CSS property is a newly available Baseline feature that lets form controls naturally adjust their sizing to fit their contents. Find the documentation here → goo.gle/4a1HJMM

If you've got a WordPress site, give the new Capo plugin a try! It automatically sorts your <head> elements by importance and surfaces any warnings wordpress.org/plugins/capo...

What if we could remove the friction in the email → goo.gle/4fsFpjG The proposed Email Verification API would let your site validate the email address right in the browser! No email sent, no confirmation click needed.

Nice teardown of how the Modern Web Guidance skill actually works by @nucliweb.net joanleon.dev/en/modern-we... A lot of thought went into being as token-efficient as possible!

BIG NEWS: Bocoup is now Igalia! The two worker co-ops have agreed to join forces, with several members of Bocoup coming aboard at Igalia, along with the brand assets and web site. More details in our official announcement: www.igalia.com/2026/Joining...

Baseline is not a ceiling 🙈 If you only use Baseline Widely Available ✅ features in your project, you’re missing out! So many features you can use with fallbacks or as progressive enhancements. Newly: web-platform-dx.github.io/web-features... Not Baseline: web-platform-dx.github.io/web-features...
