Do you have an RSS feed for your blog? Even if it's there it's not discoverable. It would be really nice to have!

2027 web platform feature ranking. The @webdevs.firefox.com team asks you to rank around 10 of the 100 Interop 2027 proposals you care about. Last year’s 1900+ rankings shaped both Interop picks and Firefox’s own priorities. #interop #firefox

A list with “Advanced layout of sorts”, “Exciting animations”, “A mind-blowing JS thing”, and “Innovative typography feature”, and a cursor dragging “Improved compat for some old thing”.

Yay, with the 27.0.1 update, macOS is almost usable now! Well, apart from the “which one of the black boxes is the space you’re looking for?” game. It’s still there 🫠

macOS System Settings showing the Software Update pane. An update to macOS 27.0.1 (3,31 GB) is available, described as providing bug fixes, with "Update Tonight" and "Update Now" buttons. The update is circled in red.

Top of the macOS Mission Control screen showing a row of ten Spaces thumbnails. The first space previews the painted field wallpaper, while the other nine are solid black rectangles.

A man stands at the ticket counter of a movie theater. An employee asks if he’d like to upgrade his ticket. “Would you like to upgrade to Cinema VIP? You can pause the film for bathroom breaks.” Our man is intrigued by the offer. Next slide.

Inside the movie theater. The film has been paused and the movie screen lets the audience know: “PAUSED FOR VIP.” Our man stands at the center of the theater with his hands raised and a VIP badge attached to a lanyard around his neck. He’s part of the Cinema VIP program but at what cost? The other patrons have become increasingly upset with the pauses. A chorus of angry voices rain down on the VIP from around the theater. “Sit down, toilet boy,” one woman yells. She’s had enough of his potty breaks. “Oh COME on.” “Get this guy outta here.” “He ruined the trailers, too.” “Take his badge.” “3 times?!” “Put a diaper on.”

MDN's browser compatibility table for the HTML popover attribute. Its columns cover desktop and mobile browsers, showing which versions support the attribute and its "hint" value. A "Settings" button sits above the table.

The Browser compatibility settings dialog on MDN. Browsers appear as chips grouped under Desktop, Mobile, Server and XR, and each one can be added to or removed from the table.

Browsers situationship: when browsers agree but the spec doesn’t. Rakhi explains why a spec sometimes moves toward browser behavior instead of the other way around, and how tests and Web compatibility bring them back to one result. #browser #interop

An SVG inside <img> has always been a styling dead end: you can place it, but you can’t paint it. CSS Linked Parameters fix that in Firefox Nightly, so I traced Warhol’s Marilyn and repainted it nine times from one 50 KB file 💅

Nine Marilyn Monroe portraits in a three by three grid, each in a different set of colors: pink and yellow, turquoise and orange, plum and navy, lilac and sky blue, magenta and orange, mint and amber, grey and slate blue, green and brick red, teal and magenta.

The root scroller and how not to lose it. Kilian Valkhof shows how an app shell with a fixed-height wrapper and overflow replaces the page's own scroll container, losing keyboard scrolling and pull-to-refresh, and what to use instead. #css #scroll

My latest experiment: I built a toy UI framework where the logic is written in Rust, but it mutates CSS instead of HTML. It was quite a fun experience with surprisingly good performance. A couple of wheels were reinvented along the way :)

Sidenotes with CSS anchor positioning. Vincent Bernat pulls notes into the margin with anchor-name, position-anchor, and typed attr(), then uses max() with anchor() so a note lines up with its reference mark or drops below the previous one. #css #anchor

Article text with sidenotes in the right margin, one reading “My PhD advisor told me this is unwise.”, an HTML snippet, and the title “Sidenotes with CSS anchor positioning” by Vincent Bernat.

The browser’s main thread is expensive. Sunhyoup Lee explains how to fit JavaScript, styles, layout, and events into 10 milliseconds per frame: split long tasks and yield, batch frequent events, or move work to the compositor or a Worker. #performance #js

Make your logo brighter than white. Chris Bennett built a tool that turns a logo into a gain-map JPEG, so the colors you pick shine up to 7.5 times brighter than plain white on HDR screens and stay a normal JPEG everywhere else. #color #image
