view-transitions

You can animate DOM state changes using the View Transitions API by wrapping your DOM update function inside document.startViewTransition, which automatically captures and animates the transition between old and new UI snapshots.

To target specific elements for shared-element transitions, apply matching view-transition-name CSS properties to the elements you want to animate, and style them using the ::view-transition-old and ::view-transition-new pseudo-elements.

Yes, you can coordinate view transitions with framework rendering by returning a promise from the document.startViewTransition callback, ensuring the DOM update waits for data fetching to complete before the animation finishes.

You need to check for document.startViewTransition availability to verify browser support for the View Transitions API, and plan CSS-based fallbacks for browsers where this feature is not supported.

The best way to handle component state toggles with smooth UI animations is using document.startViewTransition, which automatically interpolates between the old and new rendered DOM states without manual state management.

Your view transition may freeze the screen if the DOM update callback does not return a promise for asynchronous data fetching, preventing the View Transitions API from coordinating the animation with framework rendering.
