Mage v3 is out 🚀 A full rebuild of my bin/magento helper for Magento 2 and Mage-OS. It works from any folder, detects Valet, Warden and DDEV, and has one mage add for packages, themes, patches and sample data. grimlink.com/blog/2026/ma... #Magento2 #MageOS #Hyva

My Journey with Emulation through the Years grimlink.com/blog/2026/em...

Sometimes you look at an old HTML document and see some weird tags and snippets from bygone eras. I've complied many legacy HTML bits I've noticed and documented what they were and why there were present. Many of them are rather obscure. Satisfy your curiosity: vale.rocks/posts/html-r...

We are excited to share a new extension for Fylgja CSS, the attr v2 polyfill 🎉 This extension brings better support for the attr v2 syntax, by letting older browsers fall back to a static list of values. fylgja.dev/blog/introdu... #fylgjacss #css @vite.dev #postcss #lightningcss

To target multiple classes with the same prefix, you'd typically have to resort to brittle attribute selectors. To make things easier, CSS is getting a new selector: the “Class Prefix Selector” (`.foo-*`). Check brm.us/class-prefix... to get the details. (Browser Support: None 😛 — just resolved!)

Many thanks to @anthropic.com for offering six months of Claude Max. It made building Fylgja UI a much easier process.

AI brought Design Tokens back into the spotlight this year. At the Hack-AI-Thon I explored using Claude Design and Google Stitch to generate them, and shipped the result in Hyvä Theme 1.5.2. Wrote up the whole journey: grimlink.com/blog/2026/hy... #design-tokens #hyva #ai #fylgjacss

Last month, I was speaking at @cssday.nl on the new <meta name=text-scale> tag. I've just published a blog post with my slides and summary. www.joshtumath.uk/posts/2026-0...

💡 CSS Tip! An old design pattern solved by a modern CSS feature. css-tip.com/responsive-s... Learn how Gap Decorations makes it easy to add a separator between items using simple code with no hacks. It works with different alignment settings, and you can easily adjust the shape as well.

Command aliases map short mnemonics to any command in Zed's command palette. Define "gb", type it, and run `git: branch` without hunting for the full name. Read about it, and other hidden gems, in the latest post: zed.dev/blog/hidden-...

Chromium rolled out gap decorations with v149 and boy, am I excited about this. The Web Weekly site has lots of solid and dashed gaps and making this work was quite painful. Here's a good explainer. https://utilitybend.com/...

Still feeling inspired after my first time attending #CSSday. I put together a reflection on the overall experience and some of my favorite learnings from the event. Read it here: grimlink.com/blog/2026/cs...

#cssday @nerdy.dev awesome your adopting colors with only hues and chroma, looking forward to Open Props v2, also if you don't mind 😁 I also want to add `hue-rotate` to my version in Fylgja CSS

#cssday @una.im does overscrollcontainer work with the HTML Dialog? I suspect yes, but had to ask 😉

YES, Dark Mode Toggles _should_ be a browser feature. I wrote about this before: brm.us/dark-mode-ov... Find the link to the Chrome Bug in the post, and hit the star next to it to "upvote" the bug. (I even have a prototype extension to provide this for you: brm.us/chrome-dark-...) #cssday

#CSSDay friends: don’t forget to fill the State of CSS 2026 survey! survey.devographics.com/en-US/survey...

#cssday @matuzo.at should we still call it a css reset, feels like we are just setting better defaults so a base css or something else would make more sense?

Fylgja v2.2 is out fylgja.dev/blog/npx-fyl...

One day left until #CSSday, so excited to finally attend one and with a banger lineup.

I love you @zed.dev and your great but your extension publishing is just bad, I suggested a extension for Magento 2 snippets and a colleague added one for a LSP and both are still open after 2 months of waiting ☹️

CSS style() queries landed in Firefox 151 making them newly available across engines. Here's how they work:

My new Mac is finally rocking its new stickers! 🥰 This time it’s a mix of gaming and dev stickers, and I’ve left some spots open in case I find something cool to add.

Congratulations @kevinpowell.co on the 1 million subs 🎉👏 youtube.com/live/e5JY5Kz...

It’s rare that I switch editors, but #ZedEditor has completely won me over these past few weeks. It’s a total breath of fresh air, insanely fast and the AI integration is seamless.

corner-shape is one of those things where when you first see it, it's like "oh cool, I can make a scoop!" It's something new, which is fun, but it can be hard to think of good use cases. But, as @cassidoo.co looks at here, it's going to open up a lot of possibilities 🙂 cassidoo.co/post/css-cor...

We’re finalizing the core UI Library! 🚀 After dropping the Badge and Toast components at the end of the year, we’re now busy wrapping up the final set. If you’re looking for a specific CSS component, it’s likely on our list! 🛠️ #DesignSystems #UIUX #Frontend #CSS

#aria completing practical-accessibility.today by @sarasoueidan.com fantastic course on #a11y

What a fantastic two days at @perfnow.nl! Learned so much, not just from the talks, but from all the great people. Time to digest those notes 😅! It was a blast being the #magento dev in the crowd explaining @hyva.bsky.social to folks who hadn't heard of it yet 😁 #perfnow #hyva #mage-os

Question for @tunetheweb.com for @perfnow.nl, can you detect if the 'prerender until script' is supported and fallback to prefetch if not yet supported

Enjoyed this writeup by @dbushell.com about the usability of custom cursors in #CSS dbushell.com/2025/10/27/c... When I visited the Wondermake website I was surprised the cursor was that big. I didn't realize it was responding to my OS settings. Neat. Interesting that Windows doesn't do the same.

I wrote an article to celebrate scroll-driven animations finally landing in Safari 26, here are some things you probably want to know before using them: cydstumpel.nl/start-using-...

👀 Browserslist 4.26 - Now supports Baseline Queries Thanks @en.sitnik.ru @tonypconway.com , this will be way more convenient in many cases!

Interop 2026 has started asking for proposals. web.dev/blog/interop... What would you like to see being made more interoperable across all the major browsers?

Anchor positioning is not yet baseline, but you can use it in production with a polyfill - anchor-positioning.oddbird.dev (and in fact, we're using it on oddbird.dev). If you're curious about anchor positioning, now is a great time to learn, and my email course will help you dive deep!
