The Immich stable release is out today! It's an amazing self-hosted alternative to Google Photos and iCloud Photos. github.com/immich-app/i... github.com/immich-app/i... (bonus points: it happens to be written in SvelteKit 😄)

Easily one of the most delightful people to work with. Andy is the talented designer behind the dogs on my blog posts, and if you have a design role open he is well worth talking to about it!

We’re live!! My brand-new course, “Whimsical Animations”, is now available. 🥳🎉 whimsy.joshwcomeau.com I’m so excited to share all of my animation tools and techniques with y’all. 😄

Management is common progression path in tech and often, a very tough change for developers. Liam Egan is here to help with some really sound advice to help people navigate this complete switch in their day-to-day. piccalil.li/blog/transit...

My next course, Whimsical Animations, launches in “Early Access” in 1 week from today! 🎉 The most important thing to know is that registration will only be open for 7 days. You’ll be able to register from Sept 24th to Sept 30th. Otherwise, you’ll need to wait for the full launch, sometime in 2026.

Wrote a little thing about subgrid that I hope you find helpful. Short and sweet, with nice, clean code 🥰 webkit.org/blog/17339/s...

✍️ How modern browsers work addyo.substack.com/p/how-modern... - my write-up on browser internals for web developers

Earlier this week, I learned from @patrickbrosset.com that DevTools in Chrome and Firefox are built using web technologies. That means that yes, you can inspect Chrome DevTools using Chrome DevTools 🤯

This is a great to-the-point summary of when to use "Your" vs. "My" in user interfaces. Tiny details like these add up fast!

Just stumbled over this absolute gem of a personal website by @nicmakesstuff.bsky.social. What a creative and beautiful site full of character. 10/10! www.nicchan.me

Had an absolute blast at @smashingconf.com! What a great bunch of folks all around. My favorite quote coming from @bradfrost.com: „Pixels are cheap“, explaining that failing is a necessary part of progress. Thanks for creating such an amazing atmosphere, and I hope to join again next year! 🥳

Great writeup of the math behind refraction and Liquid Glass in the browser! (Chrome only at the moment) kube.io/blog/liquid-...

If you're at @smashingconf.com Freiburg next week, come check out the pre-conference Jam Session on Monday night. There'll be a few awesome lightning talks, in one of which I'll show you everything wrong with JavaScript dates, and what's being done to fix them! 🎉 smashingconf.com/freiburg-202...

✨ Big O ✨ Let me take you on a visual introduction to what big O notation is in my new blog post: samwho.dev/big-o. With big O notation you can better understand how algorithms will perform in practice, finding orders of magnitude improvements often with very simple changes to your code.

CSS Tip of the Day: `overflow: clip;` You can use it to clip overflowing content in one axis while keeping the other axis overflow visible. This is not possible with `overflow: hidden`. Try it here: codepen.io/NikxDa/pen/...

If you're ever building something that requires users to sign or draw in the browser, you'll want to use @tldraw.com 's Perfect Freehand. Super smooth freehand lines with any input device! www.perfectfreehand.com

Email addresses are very simple, and you will score highly in this quiz. e-mail.wtf

I reimagined the hero section of Time's website with modern CSS. I hope you like it! ishadeed.com/article/time...

Lovely primer on anchor positioning by @saron.bsky.social on the WebKit blog! Check it out: webkit.org/blog/17240/a...

I saw a post on Mastodon where someone pointed out the word "passport" comes from a time where you used it to... pass a port. The revelation is real with this one. Is this as mind-blowing for native speakers as it is for me?! 🤯

Super useful tip for working with inline CSS and/or JS using //# sourceURL comments

TIL: CSS variables can contain non-ASCII characters. That means that yes, you can have emoji in a CSS variable name, and yes, zero width spaces are valid, too... in case you want to spice up your stylesheets!

@benholmen.com made it to #1 of HN with @kilopx.com – and with it, by pure chance, my little cat drawing. What are the odds! Congrats on how well the project is received over there, well deserved :)

Going to be talking about @tanstack.com Start at React Karlsruhe tomorrow night. Come check it out if you happen to be nearby! www.meetup.com/de-DE/react_...

I've encountered problems with memoization dependency chains many times, but I never found a good solution until React Compiler – or so I thought. The latest ref pattern outlined here is really smart!

Daily reminder that AI is still terrible at producing sources

TypeScript 5.9 RC is available to try! Let us know how it works before next week's stable release! devblogs.microsoft.com/typescript/a...

Opinions are divided on this one for sure, but I need to rant about the new macOS design. Why would the sidebars float? Why would they be translucent if the background it now sits above is white? Everything about this looks so off, and I will hate having to look at it every day once Tahoe releases.

One of the most powerful tools in my toolbox is SVG. When combined with CSS and JavaScript, we can do some truly remarkable things. ✨ 📝 I’ve just published a brand-new blog post that covers the most critical fundamentals. It’s chock full of interactive demos. 😄 Check it out:

I just wanted to say, I’m probably more proud of this Ted talk than just about anything I’ve ever done so I’m gonna be absolutely useless for the next couple of weeks as I promote the shit out of this because I want you to watch it because it matters in the moment we are in youtu.be/dVG8W-0p6vg

Inspired by @samwho.dev 's infuriating jsdate.wtf, I decided to go and look at how Chrome actually goes about parsing JS dates. Turns out it's actually super interesting to look at this at the engine level! You can have a peek at the parser implementation here: github.com/v8/v8/blob/6...

This is fantastic! As opposed to JS Dates, which are… not so fantastic 😂

Looking forward to joining @smashingconf.com in Freiburg this year and meeting a bunch of fellow web folks! September can't come soon enough :)

Highly recommend this awesome talk from CSS day by @ntim.bsky.social‬ talking about form control styling! A new appearance mode and more standardized input pseudo-elements would be awesome to have 🤩 Very interesting proposals in there. www.youtube.com/watch?v=WgS...

My absolute favorite use of this is to ensure that in a switch/case, all cases have been covered. This can be done using `value satisfies never` in the switch's default case (where `value` is being switched over). It will type error if you forgot to check a case!

Hey @kmc.bsky.social, I‘ve been looking at new calendars recently and remembered Daybridge! The old beta seems to have sunset. Are there any news you‘re able to share? :)

Promised I'd share some of the small quality of life updates I've been working on this weekend. Up first is the ability to link to specific headings with a small link that pops out to the left on hovering!

Modifying the snooze duration? This must be iOS 26's biggest change #wwdc

This is huge! Great work again by the web folks at Apple 🎉

Exploring the idea of a table of contents which I've always liked. This got me thinking that instead of a separate progress indicator, the whole element could be an indicator in itself. Some `clip-path` magic later, this seems interesting! Not quite where I want it yet, but it's a nice little idea

Spending the weekend taking a break from working on my latest post and doing some quality of life updates to my site instead. I'll probably end up sharing a few bits and pieces in the next few days with some tips and tricks!

Had a blast giving feedback to @nik.digital while he worked on this post. He’s got such a sharp design sense, his site looks absolutely beautiful, and it was a challenging topic to cover on mobile. The result is superb. nik.digital/posts/tab-ro...

Got this cute little demo working 😍 Especially proud of the fact that it has a nice border shape in line with the other objects on the page, and that the overlaps are properly sized (even the MDN docs get this wrong!)

TIL that the CSS isolation property also isolates elements using `mix-blend-mode`, because apparently blend modes are scoped to a stacking context. Super useful!

Dabbling in fireworks, inspired by @joshwcomeau.com's Whimsy landing page. He does a _lot_ more in his implementation than I do here, but it's a very fun thing to explore!

👀 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.

This is so random! and muuuuch needed A new Random namespace with 22 methods for working with randomness in JavaScript. proposal just hit Stage 1

I've been working on a digital product, and by far the biggest hurdles in launching are the privacy policy and t&cs. There are a million generators that spit out huge amounts of legalese, where I just want a short and concise but GDPR-compliant form.

I‘ve been tinkering with interactive examples for my next blog post and its very slowly starting to come together!

Published a new interactive blog post on tab roving, a nice little technique for making grids and other element groups more accessible for keyboard navigation! Check it out: https://nik.digital/posts/tab-roving
