Anyone using HTTP/2 server push with libcurl?

If you use this feature in libcurl, please let us know. It is being deprecated all over, including in specs, browsers and servers and I believe the time has come for us to drop it from libcurl in the future as well.

So I'm curious to know if anyone actually (still) uses it.

3D CSS guide: perspective, preserve-3d and translateZ. @carmenansio walks through building real 3D scenes in CSS, framing it as the leap from Super Mario Bros 3’s painted depth to Super Mario 64’s true camera. The tour covers perspective and perspective-origin to place a camera, preserve-3d to keep real depth, reusable cuboids, animated camera moves, and translateZ, rotateX/Y/Z, scale3d, and matrix3d. All six properties are Baseline. #css #3d

You know the <img> element, right? It's one of the most-used elements, and yet it hides a secret. 🤫

What kind of secret? Read my latest article to know about it (You will be surprised!)

#CSS #HTML

The Declarative Partial Updates proposal now has a path to a solution for the long-standing feature request of HTML imports: https://github.com/WICG/declarative-partial-updates/blob/main/fragment-include-explainer.md. This looks really good, and flexible for all sorts of use cases (sanitized or unsanitized, in-place or somewhere else, atomic update or streaming,…).

LinkedIn actually adds a ‘seems like AI slop’ button https://www.theverge.com/ai-artificial-intelligence/973384/linkedin-seems-like-ai-slop-button

16 years ago, the first public working draft of Web Open Font Format (WOFF) was published. WOFF is how downloadable fonts on the Web went from "no-one uses it" to "most sites use it".

I reflected on this milestone in a blog post today:
