Adobe Animate/Flash to Rive. We've been making progress on our converter. This one is an old Formula 1 file from our team.

I noticed a sudden spike in the number of weekly downloads — from 2k to 500k — of my package to calculate the CSS specificity of a selector.

Geolocation Element Demo

Less JavaScript, more HTML.

The new <geolocation> HTML element handles permission states and blocked permission recovery for you. Just add the tag, listen for the location event, and let the browser handle the rest→ goo.gle/4pPXZFK

And yet, the only way I was able to build this UI was by giving the AI the right answer, telling it to use subgrid instead of `display: contents`.

If I didn’t understand the mechanisms and limitations of CSS Grid layout myself, I wouldn’t have been able to provide this guidance.

Also, the new units like dvh, lvh, etc. Were they not supposed to help size things according to the viewport regardless of floating bars? I swear there’s nothing I can do that allows me to size an element full screen so that it covers underneath the bottom floating address bar. Whyyyy.

Not a nitpick, but a praise: I had to setup Nuxt on a relatively limited CPanel setup last year and was extremely surprised that its native Passenger Fusion makes it as easy as it gets. Just gotta make a commonJS wrapper to boot the app. Preach 🤘

Is the world healing?

I’ve been wondering the same lately too. I had to work with WordPress again lately (against my will) and wanted to use the occasion to update my stack, but because of the current block based / file templates overridable by the database and such, I was wondering if there even was an ideal solution.

More performant than other anim libraries out there! It beats Motion in 99% cases, WAAPI in lots of cases yet Julian added an api layer to facilitate its usage, and toes to toes with gsap - outperforming it in many cases like interacting with other libraries like three.js 🔥🔥
