To smoothly animate things like borders as part of a View Transition, you need to duplicate that animation onto the ::view-transition-group. For best effect, have the View Transition separately capture the background and foreground of the element you’re animating.

New in Chrome 134 on Android: the ability to place the Address Bar (aka “Omnibox”) at the bottom. To enable it, go to Chrome’s Settings, locate and tap “Address Bar”, and choose “Bottom”.

Beware when manipulating the coordinates of the View Transition’s ::view-transition-group(*) pseudo. Depending on where you read those coordinates from, you might end up with layout jumps when writing them back. This post details the pitfalls and how to deal with them, unlocking more performant animations on the ::view-transition-group() pseudo along the way.

Martin Winkler published a package that polyfills Element.matchContainer to get notified in script when a Container Query matches/unmatches. Under the hood, it uses a StyleObserver.

Support for Nested Container Queries and the CSS if() function inside CSS Custom Functions make @function very powerful.

Chrome is currently prototyping CSS Functions, which is very exciting!

If the dimensions of the ::view-transition-group(*) don’t change between the old and new snapshot you can optimize its keyframes so that it animates on the compositor.

The ::view-transition root overlay captures all clicks … but you can undo that.

Back in December I joined Kevin J Powell on his channel to talk about Cross-Document View Transitions

You can now use `attr()` with any CSS property — not just content – and it can parse values into data types other than <string>.
