This game originated from a project for @joshwcomeau.com's React course (I super recommend it - it's a great course). I'm so happy with how it turned out and I thought I'd share it with you all here yay

✍️ New Article: Use Cases for Field Sizing
A quick look at field-sizing and where it can be used. I hope this will land in Firefox and Safari soon. The good thing? We can use it as an enhancement.

Happy Halloween! 🎃
I think Halloween is my favourite holiday. It’s just so *weird.* I passed by a Subway restaurant that had a poster like this in their window, and it just struck me what an unusual thing this is for a business to do. 😂

There’s something magical about physics-based animation. When we use springs instead of Bézier curves, we tend to get way smoother motion.
Up until recently, we’ve needed to use JS libraries for this, but a modern feature lets us emulate springs in native CSS. ✨

Looking for recommendations for doing web dev work (React/Next) on Windows. Is it still ideal to use WSL, or should I install stuff natively on Windows? If native, what’s the best way to manage multiple Node versions?

I am in the midst of the *worst* customer support experience I have ever had, and surprisingly, it’s with Apple.
I have a top-of-the-line MacBook which is less than a year old, and have spent dozens of hours over the past 3 months trying to get it repaired, with zero success.

There’s a new type of CSS scroll-state query coming: “scrolled”.
This one remembers the last direction you scrolled into, which you can use to build “hidey bars”: when scrolling down (or having scrolled down), the hidey bar hides itself. When then scrolling back up, the hidey bar reveals itself.
