I started a little pet project recently, a VS Code extension that discovers Custom Elements Manifests in your workspace and starts a local MCP server that AI assistants can connect to. Features are still very early & rough. Love to hear your feedback! marketplace.visualstudio.com/items?itemNa...

Lit is joining @openjsf.org! 🎉 Today at JSConf, The OpenJS Foundation announced Lit is officially joining as an Impact Project! We're beyond excited for this move and look forward to continuing our work to build the open web with OpenJS! Read more on our blog: lit.dev/blog/2025-10...

All of the colors are calculated based on a single CSS variable using relative oklch, so you can change the theme with just one line. --tint: green; Modern CSS is amazing! 😲

super excited for @lit.dev to be joining the OpenJS foundation! Kudos to: @justinfagnani.com Steve Orvell @graynorton.bsky.social Kevin Schaaf Peter Burns and any others from the Lit team and community that helped pull it off! Huge and great news for Lit! lit.dev/blog/2025-10...

Started a new hobby about a month ago, brewing ciders and mead! You be seeing more of this in addition to other foodie stuff I get myself into. I’ve been trying to find more for-fun activities that don’t rely on my laptop.

I am very excited to announce the alpha release of the #WebComponents Language Server!!!

wait a goddamn minute!

I'll say it again: Every framework should be going all-in on first-class web components support. With React eating the world, second-tier frameworks are often left behind. Web components are the scalable way for these projects to support multiple frameworks, and we should all encourage it.

“The reason SPAs became the default wasn’t because they were better. It was because, for a while, they were the only way to deliver something that felt fluid – something that didn’t flash white between pages or jank the scroll position.” www.jonoalderson.com/conjecture/i...

Dear IDEs and AI tools, Can you all settle in on one path to mcp.json, so we don’t have to take the same damn config file and copy/paste for each one of you!?

Okay gang, those who sling HTML, CSS, JS, which _Firefox_ bugs are blocking you? Which features do you think need improving? What new features would you like to see? What work would you prioritise? Big or small, bonus points for linking to a bug (even more for filing bugs then linking them)!

Hey friends, did you know you can make a modal <dialog> element dismissible by clicking outside (aka light dismiss) by adding `closedby=any` to it. That's it. That's all there is to it. <dialog closedby=any> developer.mozilla.org/en-US/docs/W... Chrome 134+, Firefox 140+, coming soon to Safari.

If you've never heard of a Custom Elements Manifest, they are an invaluable tool for unlocking tons of capabilities for your #WebComponents. dev.to/stuffbreaker...

Going to be talking about curiosity and it's role in design later today at evolvedrupal.com - made a few adjustments since @beyondtellerrand.com and excited to see how folks react

Hey friends! 🚀 I’m running the biggest sale ever on my Web Component Engineering course: 25% off through July 🎉 It’s full of hands-on, flexible training to help you build components, design systems, and apps. Use code SUMMERFUN to get it now! (Link in the follow up.) #webcomponents #frontenddev

@mozilla.org you teased me and only introduced Import Attributes support for JSON. Awesome as JSON support is, I mainly want CSS support 🙏 bugzilla.mozilla.org/show_bug.cgi...

Yes! Now I can finally author plain CSS for my web components!!

If you see this, post your getaway vehicle

When you file an open source issue and the maintainer asks for more information, please just give it rather than saying you already included all the info. We wouldn't ask if we had everything we needed.

Y'ALL. Portable HTML Web Components are fucking cracked. It looks like they are **faster** than the fastest Vanilla JS implementation in the JS Framework Benchmark. I literally reran the benchmark 5 times because I didn't believe it, but every single time they came in first place 🤯

The idea of web component “overhead” is overblown — to even my own surprise! Rendering 1000s of nested WCs is *more* than competitive with the heavyweight champs of the web framework world. We’re talking S/S+ tier perf depending on the initialization method. Cont…

attr() is getting an upgrade! Starting in Chrome 133 (stable rollout happening this month), you'll be able to access attributes in CSS as typed values beyond strings.

I propose we replace semantic versioning with pride versioning

Design docs tell. Hacking throwaway code shows. One of the hardest engineering muscles to develop is to throwaway implementations. But if you get there, hacking throwaway, draft PRs works far more efficient than design docs as a "design" process. softwaredoug.com/blog/2024/12...

"It's written in Rust" is not a feature of your app. "It's blazing fast" is a hollow claim that makes me doubt it. Please stop putting these things on your homepage. Please show me why your tool/app/whatever makes my work easier/cheaper/faster-to-iterate.

One of my favourite UI patterns is using `backdrop-filter` to create a “frosted glass” effect. When I see this effect in the wild, though, it’s almost never as lush and realistic as it could be. There’s an important optimization that nobody makes. ✨ I share the secret sauce in my brand-new post:

Finally took the time to look into why my website hero image is whacked in iOS Safari. Turns out `background-attachment: fixed;` isn't supported in mobile 🤦‍♂️ Decided to just `background-attachment: initial` in that case. Not nice, but certainly not as ugly as what iOS Safari was doing with `fixed`

woot, finally got my doofy handle situation resolved

Things you forgot (or never knew) because of React joshcollinsworth.com/blog/antiqua... This is a very good post that's worth your time to read. It has a good blend of history, valid criticism, credit-where-credit-is-due, and a fresh look at current front-end technologies.
