Look at those outlines. 🔥 Hot tip!

For the last few years I have always created a valentine's post... Most of the time it's related to scrolling. For this year... I'm probably biting off more than I can chew. 😅

I've been thinking about writing my thoughts on AI and LLMs... I am not against it, I think I have realistic fears and see realistic potentials (balanced) But seriously... There is already so much of that so who cares...

Just finished running my first 4-evenings D&D campaign as a GM. Made some mistakes, got better during the days, but still need to grow. 😅 Still a noob, but respect to all GM's out there.

The CSSWG just resolved to add this to the spec 🥳 github.com/w3c/csswg-dr...

Today is one of those days where I found myself needing this utilitybend.com/blog/a-nativ... cc: @utilitybend.com

We'll be getting multiple outlines in #CSS!! Multiple outlines means no more hacking our way around accessible and creative outline styles with box-shadows that aren't rendered in forced-colors mode! 🙌 Finally!! This is such great news!! 🎉🥳

First devs.gent of the year 💯

The video is not that important, what is important is that this is a great conference! You should go 😁

Well, CSS Day is live now ( https://cssday.nl ) and I've got a bunch of related things to do but unfortunately I'm ill and can hardly concentrate. So the going will be very slow this time.

🚀 Is it scrolled? Is it not? Let's find out with CSS @container scroll-state() queries. In Chrome 144, this has gotten a little update, so I thought it to be a good time to revisit. #CSS has once again gotten the keys to the state-machine, and it's fantastic! utilitybend.com/blog/is-it-s...

Made a lil' library: codepen.github.io/slideVars/ Automatically detects CSS custom properties on the :root/html and gives you controls for adjusting them. (But it's also as configurable as you want it to be.)

🚀 I didn't think I'd start the year with another demo on customizable select, but people should know about the upcoming things. The customizable multiselect might still be a bit further down the road, but the size attribute updates should be shipped with chrome 145.😍 utilitybend.com/blog/an-upda...

Do you grab a library because you need it or doubt the browser can handle it? 🌐 @utilitybend.com is here to prove it can. 💪 At WebExpo, he'll play with new UI capabilities and CSS features like anchoring, transitions, and scroll snapping to build custom selects that stay fast and accessible.

📢 New blog post: A polyfill for the HTML switch element. Safari 17.4 added the native `<input type="checkbox" switch>` element. This post introduces a polyfill for it, covering accessibility, internationalization, styling, and its HTML spec status. blog.tomayac.com/2026/01/12/a...

CSS masonry (aka grid-lanes) has two orientations: rows and columns. I'm trying to think of good metaphors... Row is easy: a brick wall, that's where the masonry term comes from. Column: many call it waterfall, but trying to put it into an image doesn't work. Motorway works a lot better.

My 7-year old just asked me what the internet actually is... Wait, let me get my pen!

I am building a utility library of some sorts (in TypeScript) and am looking for inspiration on how to structure things and what to export. Currently I am thinking of how I structured github.com/bramus/sda-u... but most likely there are much better example repositories out there. Any suggestions?

A while ago, I wrote about why Tailwind isn't for me. In that article, I also referred to the people building it, who clearly have a love for CSS, but a different vision than mine. It's a sad thing that so many people were laid off due to the impact of AI, no matter if you are pro-tailwind or not.

CSS Day, 11th and 12th of June, just announced @brucel.bsky.social and @ohhelloana.blog as their 2026 MCs. cssday.nl Ticket sales will open later this month. We'll announce the early-bird tickets on our mailing list first. Subscribe to be notified ASAP! cssday.nl/subscribe

4 #CSS Features Every Front-End Developer Should Know In 2026 nerdy.dev/4-css-featur...

Gecko: Intent to Prototype: "Customizable Select"

Now this is a fun lunch break! (The cat didn't agree)

🚀❄️ Yep, another "holidays" blog article. As tradition, I always try to create a little "happy holidays" card as well, with something new and shiny in CSS. In the past, I did scroll-driven animations and masks, but this time, the corner-shape property in CSS. Happy Holidays, ya'll 🎆

Usable listboxes!!! (Plus styleable as a nice bonus) This includes multi-select in listbox mode.

That nice @utilitybend.com of the Open UI group (that gave HTML new fancy <select>, not the AI snakeoil merchants) wants your use-cases for multi-handle range controls. github.com/openui/open-...

🎙️LET'S GET READY TO RUMBLE!

"The author of the Smashing Magazine post may simply be taking Google at its word and that’s unfortunate for his credibility as well as the devs who read it." would love to have a chat! But not with people who directly hit below the belt. With all due respect: I believe in educating, not trolling.

Did you know that Firefox dev tools include a thing that tells you about power consumption? In the screenshot below you can see: Power: 131mW Energy used in the visible range: 4.8 μWh (0.002 mg CO_2e)

One of those features I won't use regularly, but it is just good that it exists. Happy to see it land in Firefox. Great example by @jakearchibald.com as well!

📣 New article on @frontendmasters.com about a visual problem that bugged me for years: making a card that truly feels deep. frontendmasters.com/blog/the-dee... Would love your thoughts.

I've been working a bit with Tailwind lately, and without jumping into a rage article, I took some time to gather my thoughts. It's not my favourite tool, but why? Here is an honest article on that: utilitybend.com/blog/why-tai... #CSS #Tailwind

I have a visual of an article... To press the publish button, or not to press the publish button 🤔

Barbecue, D&D, and UI. This episode is packed with my favourite things. But one thing I'm extremely happy about is that @shoptalkshow.com talked about <rangegroup> from #OpenUI. Thank you for the nice words as well! Let's make this happen (even if it is in 2030). www.youtube.com/watch?v=rx3g...
