Overview of the border-shape property

💡 CSS Tip!

We've just had the release of @developer.chrome.com 147, which means border-shape was enabled by default! 👀

css-tip.com/border-shape/

Another property to create CSS shapes, but not only that! We can do a lot of fancy stuff with it. Many cool demos/articles are on the way 🤩

I and Jason are currently working on implementing the CSS `polygon() round` keyword in Chrome.

This is one of my favorite CSS features! Thanks to @lea.verou.me for bringing it to CSS.

Enable the `enable-experimental-web-platform-features` flag in Chrome Canary

Thanks for the shoutout, and thank you for testing things along the way.

I see the necessary CL hasn’t been merged yet … so people can’t test this using the official builds yet.

!somewhatimportant 😜

You should give www.bram.us/2022/06/28/t... a watch 😉

The TL;DR is that you shouldn’t be using !important … and using layers helps with that :)

Also see www.bram.us/2022/06/28/t... if you want to dig deeper.

That’s not cascade layer madness you are demonstrating there, but !important madness.

The inversion you see here is the same effect as seen on origins themselves when !important is at play.

See www.bram.us/2021/09/15/t... for details.

— a little heavy-handed but i say better to build up from nothing than immediately lock-in to fragile foundations

Thanks for filing. I'll get some folks to take a quick peek to assess things.

@jason-williams.co.uk might be able to help you out there.

I believe there are still some open spots left on the Google Graveyard … 😜

🫵 You’re hired!

Yeah, that was … weird. We can (and must) do better here, and we’re following up internally to getting this sorted.

TIP: Our websites developer.chrome.com and web.dev have RSS feeds nowadays, so they’re easy to follow. The former is Chrome-specific (release notes, feature previews, etc), the latter about the wider web platform.

And there’s a bunch of Chrome DevRel folks here on Bsky (and elsewhere) to follow 😊

The Intl API: The best browser API you're not using | Polypane Chances are you've used Moment.js , date-fns , Luxon , or numeral.js at some point. Developers have relied on these libraries for years to format dates…

We make good use of the Intl API in our app and on our website, so it was high time we did a Polypane-style deep-dive on it.

Check out our new article, play around with the interactive examples or hear Kilian yap about it on video. Whatever works for you!

Aw, thanks for the kind words there, Marc 🥰

And yes, it was weirdly a very long time before our paths actively crossed. I’m happy I got my calendar sorted this year and am very excited to be joining BT for the very first time — it’s been long overdue.

+1 on the robots having ruined the use of the em-dash 😞 — it was the best.

Thanks!

I can come up with some individual names, but they don’t seem to form good pairs.

- intersecting: overlapping / crossing / joined
- dangling: open / shy (x-ref “crown shyness”) / separated

I’m subscribed to your RSS feed, so the signals should reach me :)

I’m missing some context to do an informed suggestion: What are the current property names you are considering and what are their values?

(Or if you don’t want to contaminate folks’ brains: what are the properties used for?)

I can do with an iframe for now :)

Depending on size and details, around one week.

Apex Domains work with CodePen Deployed Pens.

This Pen:
codepen.io/editor/chris...

Points to this domain:
bendtreehouses.com

Because I'm using Cloudflare for the DNS, which supports CNAME records "at the root" that point to domains.

Is there a way to convert a v1 pen to v2? I want to add a custom domain to codepen.io/web-dot-dev/... but can’t because it’s a v1 pen …

It was one of the parts of Houdini indeed (other parts included Props and Values (`@property`) and the Typed OM) but one that unfortunately was never gotten to.

I’m trying to get the discussion around this one started again …

Next step is that I need to gather signals from developers … and this counts as a signal :)

My talk from State of the Browser is available to watch now. This was so much fun to do, and thanks to @londonwebstandards.org @letorey.co.uk for asking me to be part of it.

Now imagine a world in which www.bram.us/2025/05/04/c... existed, and one didn't have to jump through all those hoops of fetching + parsing + rewriting the CSS …

Would you want that?
