  Folks asked if there was a way to disable Chrome's own 'back' transitions, and I didn't think there was, but… you can use a CloseWatcher to listen for the back gesture (which disables Chrome's transition), and then call history.back(). https://mastodon.social/@firefoxwebdevs/116295985768415581

  Nice to see excitement around the proposed html-in-canvas feature, but remember you can already put canvas behind/atop HTML elements. The benefits of this new feature are: ➡️ Readbacks (eg sending to a VideoEncoder) ➡️ Showing HTML on non-planar shapes ➡️ Using shaders on HTML

  I've proposed a series of changes to popover=hint. If you use web popovers, I'd love to know if the changes in the first post of this issue make sense, or, more importantly, if these changes would break your current usage of popovers. https://github.com/whatwg/html/issues/12304#issue-4121948352

  I've been playing around with Chrome's experimental HTML-in-Canvas API (I use it to create my videos), and I wanted to see if I could make text-selection work on a curved surface by moving the underlying element around on pointermove. It works pretty well! Live demo: https://random-stuff.jakearchibald.com/apps/curved-markup/ (needs Chrome Canary with the canvas-draw-element flag.

  I think it's often overlooked that AVIF is also really good at flat colour & sharp edges. Don't go straight for a lossless format just because it's the kind of image that would look bad as a JPEG. Here's an 11kb image as an AVIF, vs JPEG XL.
