View Transition

<div data-view-transition="foo"></div>

Page level transitions are automatically handled by an injected meta tag. Inter-page elements are automatically transitioned if the View Transition API is available. To set the view-transition-name style attribute explictily you use the data-view-transition attribute. The spec is still in draft and not available in all browsers but Datastar will do best effort.
