Speaking of specificity values and devtools: Chrome isn't the only browser displaying selector specificity. I rediscovered, which lists developer tools and the features they support!

Modern CSS in real life

Chris Coyier was so kind (thanks, Chris!) to transform his recent talk into an article. It covers logical properties, container queries, cascade layers and all these new colors we can use today. Aaaaaand, it's packed with beautiful examples!

Scroll-driven CSS animations

Stacked cards

Disclaimer: the following only works in Chrome 115 (which still hasn't shipped yet), but if you want to see the CSS property animation-timeline in action, spin up Chrome Canary. Bramus build some stunning examples showing off what it can do! πŸ’―

Why I don't need to clean up my Mac

Let me tell you a secret! I didn't need to clean up ~/Downloads or ~/Desktop for a year now because I changed a few macOS settings. There are two tricks to get rid of the problem of too many files on your hard drive.

Oldie but goldie: I blogged about my Mac and browser settings that help me avoid filling my desktop or downloads folder with junk.

It ended up on HN the other day, and because the comments didn't tear it apart, I guess it's still valid.πŸ˜…

The wonderful weird web – Wonky

WONKY β€” An exploration of rhythm and grooves that break the rules illustration of erykah badu, j dilla on his drum machine, and stevie wonder

I'm such a fanboy! Their articles' storytelling and interactivity are just fantastic. This time the journey goes into rhythm and why some songs just "have the groove".

Groove and swing

Reminder: optional catch bindings are cross-browser supported

Editor complaining about a catch block without a parameter.

There are situations when you're trying to catch an exception but don't want to do anything with it. One of JS' quirks was that you couldn't just leave the catch empty. ☝️

Here's a trick: omit the () and use optional catch bindings. They've been cross-browser supported for a long time, and Axel Rauschmayer explains what they're about.

Ignore the error

React server components (RSCs) from scratch

In this technical deep dive, we'll implement a very simplified version of React Server Components (RSC) from scratch. This deep dive will be published in several parts: Part 1: Server Components (this page) Part 2: Client Components (not written yet) Part 3: TBD (not written yet)

I've only read the first third of Dan Abramov's guide on React server components because it's long! Very long.

But Dan clearly put a lot of effort into it. If you want to understand how React and RSCs work, make yourself comfortable!

Random MDN – The 🐘 in the room. Mastodon bot.

After my RandomMDN Twitter bot was suspended, there's now a new one on Mastodon! The cool thing about Mastodon: you can also subscribe to it via RSS (add .rss to the account URL).

A huge shoutout goes to Jan for putting this back together.πŸ’™

That said, I still would love to bring a platform-independent Random MDN to life and will share my plan on GitHub soon!

Thought of the week

Julia Evans shared some myths about blogging, and it included this little gem. πŸ’™

Just because there is information on the internet, it doesn’t get magically teleported into people’s brains!

A song that makes you stop coding

I was at a techno open-air on Friday, and the DJ remixed Weezer's "Island in the sun", so that I fell in love again with this beautiful music video.
