Creating a universal app store for PWAs seems like an obvious win here vs. heuristics triggered installs. But think about smaller, more bespoke app stores! An app store for your intranet apps. An app store for your webring of online mutuals. An app store for kid-friendly apps. That's fun territory.

What do you think of this transform for TypeScript namespace? It’s meant to more accurately reflect the runtime it becomes.

Thrilled to announce Webflow's $150,000 donation to support Astro's open source development! PLUS... Webflow chooses Astro to power their just-announced AI app gen tool, coming soon.

He did! Just found his repost of this... intuitivefuture.com/@vanillaweb/...

Please stop inheriting the box-model. The supposed use-case for that is extremely out-dated, inheritance doesn't really help, and it actively makes real box-sizing use-cases more difficult! This #CSS best practice was never the best to begin with: www.oddbird.net/2025/09/04/b...

The thing about working on a big project like "the last CSS toolchain we'll ever need, built from ground up" is that there's a literal endless list of all the things that need doing. I've found myself knee deep in ASM, to writing tech docs, to dreaming up new syntax. github.com/csskit/csskit

I'm always thankful that Babel exists. To me it's the unsung hero of the JS ecosystem. It's so easy to prototype something quickly with it!

What do you wish local development could do? These are my pain points. What are yours?

Side Project Alert — I built an HTTP/3 server for NodeJs, compiled from C++ to run on Windows, Linux, & macOS (x64 & arm64), so weI can local dev over H3. There’s a small twist: it will accept module graphs for each endpoint, because…

Slightly diminish a band: grins for wins (known for “Spout” and “I mean, who really wants to rule the world, if you think about it”)

Lazy dev question: Firefox supports style queries behind a flag, but is there any indicator on when they’ll ship it? Asking for a cross browser friend.

Turns out they were bugs, but amazing people are already on it. Go web! github.com/web-platform...

Rewritten to use DSD to make the "structure" clearer. codepen.io/paramagicdev... :host() has some pretty annoying bugs, but this seems like the case where `:host()` doesn't get to hook into `exportparts` mappings 🤔 Also fascinating that chrome has divergent behavior from FF / Safari for me.

Am I totally misunderstanding CSS, or are these serious browser bugs? codepen.io/jonneal/pen/...

For 20 years Mozilla has developed one of the most useful tools for web devs. developer.mozilla.org/en-US/blog/m... Congrats to the MDN team on an awesome milestone. I'm happy that we've played a small part in its history and I'm excited to see it continue to be at the core of every web dev's job.

Seems like a problem

I think the “stop reinventing XYZ” pitch by developers is often about justifying their efforts, or sometimes even gatekeeping accepted solutions. I think devs who say this will often abandon or reinvent “XYZ” every couple years, anyway, which is fine. I’d just prefer we drop “stop reinventing”.

🚀 The #StateOfHTML 2025 survey is now open! ➡️ Take it now: survey.devographics.com/en-US/survey... 💡 Spending time to fill these out is an investment into your craft, as browsers are using the results to make prioritization decisions. You don't have to do it in one sitting (or even one device).

while the current official number is hotly debated, there are actually far more tags in HTML than the ~150 commonly cited! that number merely represents the ones we’ve discovered and domesticated — there are potentially thousands more in the creeping unexplored corners of the deep web & dark net

Hot off the presses! Firefox Nightly (www.mozilla.org/en-GB/firefo...) adds the new :heading pseudo! Easily style all headings, or use nth-child-like AnB syntax to select a range of headings! Needs `layout.css.heading-selector.enabled` flag enabled. Try it out and let me know your thoughts.

nice :)

TypeScript, deliver us from the hacks of query-string imports.

Check out our newest proposal for customizable built-in elements: ElementInternals.type! Allows you to create custom elements that inherit the behaviors and properties of native HTML elements (like a split button that actually behaves as a real button). Please share your feedback on the repo.

I love it. github.com/MicrosoftEdg...

probably one of the best production examples of what @astro.build is capable of these days ✨🚀

Just checking in. Can we declare ambient modules for import attributes? Best, jonathan?no-inline

Otherwise • Tabs would be the preferred code indentation. • Prettier would support disabling line wrapping.

👀 Coming to Chrome DevTools in Chrome 138: CSS Value Tracing When you hover a --custom-prop in a `var()`, DevTools currently shows you the computed value. From Chrome 138 onwards, you can hover the `var` part to see how CSS actually got to that value.

I get such a crazy amount of mileage out of components (and other libraries built on native platform features) I've built over the years, that building apps really has become a "lego building blocks" kind of experience, and I can just be crazy productive instead of updating a bunch of old shit

ITS HAPPENING Firefox 127 shipped today making it the first browser to support Temporal - the new API for working with Dates, times, timezones + durations

Then, Copilot complained that <search> is not a standard HTML tag and suggested using <div role="search"> instead. And some people still wonder why semantic HTML is not more widespread.

Update: She’s here!

You use accessible components but your designs still have accessibility issues. Sound familiar? I published a 2-part series exploring why these issues persist and how to solve them with a set of design system annotations that can capture critical accessibility details. github.blog/engineering/...

Been annoyed by web fonts for a while. They’re big and they were connecting my blog to Google. I stumbled on modernfontstacks.com earlier today and now I’ve ditched my web fonts in favour of these. ~140kb shaved off the first load of my site. First impressions matter.

Thanks to @kevinpowell.co the MOST ANNOYING thing about CSS is improved in @webstudio.is. Now users won't see Transforms section when display is inline.

Is naming blocks genuinely one of the hardest parts of a CMS build? I just wrote a blog about it: joloveridge.co.uk/is-naming-bl... #wordpress #cms #accessibility #a11y

In popular Toggle Group components, clicking the selected item de-selects it. I’m curious; should it behave more like a radio group, or at least offer that option? Like, if I click “Align Right” repeatedly, should “Align Right” stay selected? That’s how it works in documents.🤔

During my livestream yesterday, I talked about Figma Sites for a little bit. I've broken it off into a short, stand-alone video. I don't normally like bashing a company, but when a company of Figma's size makes a product this bad, I think it's important to call them out on it. youtu.be/ZsFIvULxkHI
