I've just relaunched CSS Demystified! Rebuilt from the ground up, on my own custom platform, and here to help you start writing CSS with confidence 😊 thecascade.dev/courses/css-...

CSS-Tricks has a new owner! Yes, I've got the keys to the castle, so to speak. And, even after 12 years of working on the site, I'll admit I'm a little overwhelmed and nervous about that. https://css-tricks.com/css-tricks-has-a-new-owner/

Amazing news!

I'm so gosh-darned excited! css-tricks.com/css-tricks-h...

I've always thought of my two channels as my main and second channels. Maybe I need to change that now? 😅

It's the time of year where decisions on investment for 2027 are being formulated so it would make a lot of sense to pull all AI spend and invest that money on stuff that actually will produce growth for your organization. There's no point in waiting for the pop. Get ahead of it instead.

I still absolutely love watching Kevin's videos about specialized details that almost no one ever cared about before (and even fewer care about now) and I will continue to do so. It's more important than ever.

Congratulations on your 10-year channel anniversary, @kevinpowell.co! Keep teaching us the cool things CSS can do. AI can write better code than I ever could, but it will never be the Meister from which I want to learn the craft.

It took me a long time to understand that it's not because you show people that something can be done better in an easy way that they will actually care about doing it. If someone doesn't care about details, it doesn't matter that it's easier now, a tool isn't gonna change their personality.

Where do people think AI gets the ideas of how to do better CSS? A combination of devs knowing that something exists + the training data. The former matters a lot with ever-emerging new standards. Riding the AI wave too hard eventually results in lack of purpose and not knowing what to prompt for.

Such a good video that mirrors a lot of my own thoughts about this. Well worth the watch!

I’ve never been as nervous to publish on CSS-Tricks since my first article in 2015. https://geoffgraham.me/nervous-to-publish-on-css-tricks/

I wish I'd realized when recording this that it would come out on the 10-year anniversary of my channel, but even if I didn't mention it, I guess it's still pretty fitting 😅 (plus it was posted to my second channel anyway, lol)

Just realized that I've been doing this CSS YouTube thing for 10 years now.

I haven't looked at too many comments on here yet, but I've noticed enough amount of "just fix it with AI" that... I donno what the feeling is, but it's not good. I do think a compilation video of people trying to one-shot prompting migrating from PHP 5 would be great though. youtu.be/cBD1AgkM1VQ

#CSS Progress - The easiest way to do fluid type now by @kevinpowell.co Exciting Video, Great explanation on the progress function and its use case. When I originally looked at this progress function, it didn’t click for me at first a few months ago.

If you're really curious about what's going on with PHP, this is an excellent explanation. (And I really hope you're not responsible for updating PHP yourself, sounds like this sucks.)

Some thoughts on the recent cybersecurity shambles: vale.rocks/micros/20261...

Amazon Web Services logged attempts to leverage the internet-melting PHP2Shell bugs four days ago. They're now being “broadly exploited” across the internet.

Not often I do timely videos, but this whole PHP thing seemed like a good thing to make a quick video on. youtu.be/cBD1AgkM1VQ

Chuffed to get a shout out in this vid from @kevinpowell.co! www.youtube.com/watch?v=bLB9... Learn how to use a few less magic numbers with progress()

Again, those security releases PHP just shipped are just … 🤯 Those two bugs let anyone run their own code on your server with a single crafted request: no login needed, and it happens before your CMS or framework even starts. And proof-of-concept exploits are already circulating … 🧵

Note: 8.5.12 appears to still be subject to a use-after-free fedi.katze.sh/@elise/11747...

Update your PHPs, everyone: “PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35 fix two critical vulnerabilities that can allow unauthenticated remote code execution. All PHP users are strongly encouraged to update immediately.” www.php.net/archive/2026...

For anyone who thinks AI is new, *MY MOM* wrote a bibliography of the literature on AI in 1959. Yes, MY 93-YEAR-OLD MOM. Yes, I'm proud of her. www.google.com/books/editio...

At one point, some investors are going to want to see some returns right?

🚀I wrote a random() thing 🤭 do check it out. When I first heard about random(), I had no idea what to think of it. So, this blogpost is actually me trying to make sense of it and hopefully, me documenting this can help you make sense of it as well 😊 www.smashingmagazine.com/2026/10/embr...

This year’s FFConf is shaping up to be genuinely unmissable. So …um, you know …don’t miss it: https://2026.ffconf.org/ I’ll see you there! 🔗 https://adactio.com/notes/22807

Every long-lived website ends up with cobwebs. 🕸️ Things that used to do something, but no longer do. Like httpequiv for IE8-10, your fb:pages id or the Windows 8 tile tags. None of them do anything anymore. But which ones can you safely get rid of? The next version of Polypane will tell you!

Really not likely, but if anyone here follows me has attended #FFConf as a student in the past, I'd love to include a quote from you (I've got a couple of posts, but they're pre-pandemic so I'd love something a bit more recent). Can be a social post or email to events@leftlogic.com

I've been hearing about JPEG XL for *so* long now. Now that it's finally starting to gain support, @jakearchibald.com has a great look comparing it to AVIF. I know one of the selling points for JPEG XL is progressive rendering, but it's coming to AVIF too. jakearchibald.com/2026/jpeg-xl...

I just shipped CSS Custom Highlight Universal Selector! Coming in Chrome 158. With ::highlight(*), you can write a shared rule that applies to every custom highlight instead of repeating the same styles for each name. See the Blog post: blog.seokho.dev/development/...
