‘What we really need to do is create a powerful sense of dread. The longer the note, the more dread’

SCOTUS pushing a bunch of bullshit to prod right before going on vacation. I see you.

Design systems have always intrigued me, but they are something that I don't have any experience with, so, I've teamed up with someone who does have that experience!, @michaelwarren.dev! It's still early days, but if you want updates as we work on it, sign up here: thecascade.dev/courses/desi...

🎉 NVIDIA Elements is now open source. After years of work + API hardening, it's stable enough to share. A framework-agnostic design system for AI/ML robotics & autonomous vehicle UIs. Web Components that run in any stack, plus CLI/MCP/Skills/lint tooling. nvidia.github.io/elements/

Oh my days!

we have a rare window of availability at @codetv.dev, so if you're looking to make something special that helps your company connect with devs, now is a very good time to get in touch. I love working with teams that have the courage to experiment & take big swings — if that's you, get into my inbox!

We migrated an Astro site from React and Ark UI to native Web Components. This resulted in 100 KB less JavaScript and no functionality lost. In the process, we built a tiny library called nanotags that makes Custom Elements enjoyable to write. Here's how we did it:

I say this in all humility as a man with a 3ft x 12ft x 1ft deep trench in his backyard and an enormous pile of rocks… If it’s a tool that has a stick for a handle, I probably own it at this point.

With style queries now in all browsers, here's my take on the best way to do dynamic color theming with modern CSS: - Custom properties - light-dark() - contrast-color() - Style queries - Relative color syntax (^Features available in all modern browsers) Read about it ⬇️⬇️ una.im/modern-css-t...

Dave Rupert LLC is happy to announce the launch of GameBox, a box for games. Games are fun. You own tons already. Now have a box for them. Starting at $39,999 MSRP.

The HTML cat is out of the Web Audio bag. I've finally released HYPERBLAM. It’s my system for sampling, processing, and sequencing sound and music directly in HTML. hyperblam.how

There should be digital garage sales. Unused fonts - $1 ea. Unplayed video games - $3 each or 4 for $10 Bundle of online courses I barely even started: $50 OBO

When it comes to web stuff… It’s one thing to have an idea. It’s another to be able to build the idea. It’s another to be able to explain the idea with words. It’s another to be able to build examples that illustrate the idea and the problem it solves. That’s quadfecta is difficult and rare.

Another thought while working on this. I'm solving problems that look simple, but require care and thinking. I'm confident to say that LLMs won't be able to figure this out, as it's solely depend on your CSS knowledge. I will compile all those thoughts and share them as an article or a video.

Correction: I said "shipped" but it's actually behind the #enable-experimental-web-platform-features flag, which I forget I have turned on in stable. So it's subject to change. Thanks @bram.us for calling that out.

This change to interest invokers shipped and it’s wild to me. …wow.

I would love it if "Subtractive Engineering" became more popular. An analogy (because we love those), you can get rich extruding plastic and sending it all over the world, but removing plastic and preventing plastic from entering the environment is a much harder task. htmx.org/essays/code-...

Based on the feedback at @css.cafe I opened a few issues to discuss at open UI on the enhanced range inputs. I also tried to make some new examples with waves and circles. 😅 brechtdr.github.io/enhanced-ran...

You tellin’ me a CNC machine made this music factory?

They said it couldn't be done. We did it anyway. SSR is available in Web Awesome 3.8. We're calling it experimental, but it won't stay that way for long.

This has been a common theme today at #cssday and it’s true: complaining about broken stuff in browsers is a great way to get them fixed! Don’t silent. Let us know. Have a new idea: write a blog post!

Came across an interesting CSS cascade issue where global padding/margin resets override `:host` styles in the Shadow DOM. Found a workaround, but don't love it. Curious if others have thoughts. codepen.io/davatron5000...

3D printing is a fun hobby filled with an interesting cross section of people: makers, DIYers, creative modelers, craft moms, organization freaks, and lots of dudes who really, really, really, really love guns.

Hi BlueSky pals 📣 Having just completed a fun project with the folks at Clearleft, I’m on the lookout for my next project. I’m open to part-time or full-time contracts outside IR35 and I can help you with: - design systems consultancy & management - content design - design systems documentation

Rented a tiller and absolutely went ham on my whole backyard mud pit. That machine beat the shit out of me tho. Yeesh, I’m exhausted.

Look, plantar fascitis sucks but I think this guy has bigger issues going on

We should be two “D&D Honor Among Thieves” sequels deep.

If you give me six hours to 3D print a tree, I will spend the first 4 hours printing things for my 3D printer itself and then run out of filament and the time it says it takes to do the actual print.
