Matrix Playground
Apply any combination of translate, rotate, scale, and skew to an anchor element and watch the Chrome 144 tooltip track its transformed position. A second label shows where the same anchor would place in pre-144 browsers — at the un-transformed origin.
Checking CSS anchor positioning support…
The Chrome 144 fix: Before Chrome 144,
anchor() resolved positions against the element's layout box, ignoring CSS transforms. Chrome 144 makes anchor positioning transform-aware — the anchored element now tracks the visual (post-transform) position.
