About to have CSS ANCHOR POSITIONING FULLY CROSS-BROWSER!!

Our Wirecutter testers think this cheesy contraption belongs at every holiday party. Read writer Maki Yazawa's review on the medieval-looking cheese cutter that “provides boundless entertainment for my inquisitive guests." nyti.ms/4ir2S5G

it’s wild what you can put together in Kirby Air Riders.. I enjoy this aspect of the game just as much as the races #kirbyairriders #silksong

We’ve got a biiiig update for you. A complete redesign of Sketch. Maybe you’ve tried the beta, maybe you’ve seen the teasers. Now you can update and try it all for real.

And there’s more! 🧵 ↓

keyframes • Playground • Svelte Web development for the rest of us

This is tricky, but the more I think about it, maybe it's an expected behavior? @keyframes defined in a component is locally scoped, unless being used as a value in a local css variable – then I need to declare the @keyframes globally to make it work

class • Svelte Docs class • Svelte documentation

I have always used classnames/clsx, but I didn't know that Svelte essentially supports that pattern natively!!

The web platform has changed so much, but whenever I reached to a React UI library it felt like they were built 10 years ago. None of the major React frameworks seem to even use <dialog>, a thing that has full browser support 3 years ago

I guess some sort of a local static site generator with a nice UI on top

Is there a site builder that runs locally aka works offline, allow building both with code and via GUI, has a simple built-in database, and output pure static html (framework opt in)?

I'm quite proud of this gradient, thought it turned out really well. The noise filter will definitely mess with video compression, so better see it live: codepen.io/d4rek/full/d...

Do you know which song this pen is referring to?

Doubling the animation speed seems to make the pen works again in both conditions. I wonder if animating via RAF would had fixed this issue – I suspect not – but it's a good thing the browser throttle animations, I think

I looked at this pen again & it no longer showed the same effect. It was my laptop battery level – when plugged in, the animation was much smoother!

That's pretty obvious, but I haven't worked on an animation where that's clearly observable. In the vid below you can tell the moment I unplugged

Stoke to finally get my hand on the third First Cat in Space book, love reading it and the others with my little one

So slick! Wanted to witness this beauty on the live site but gave up scrolling half way through 😔

This is so cool. Modern CSS is almost unrecognizable from when I learned it

CSS + SVG to animate stroke-dashoffset combined with scroll-snap

extra bonus: use a scroll animation to toggle scroll-snap at either end of the scroller
