3 ViewTransitionStyleTracker: The Mechanics of Element Capture and Naming

The provided text describes the ViewTransitionStyleTracker, a core component within the Blink rendering engine that manages how elements are captured and animated during a web transition. It functions as a central "brain" that identifies transition elements by scanning for specific CSS names or utilizing the match-element keyword for automatic identification. To ensure visual fidelity, the tracker records essential geometry, layout, and paint order data, allowing the browser to recreate the page's stacking context within a dedicated transition overlay. The system relies on internal data structures and mapping to link DOM elements with their captured snapshots using stable identifiers. By maintaining these relationships, the tracker ensures that old and new states are matched accurately, even when names are generated automatically based on element identity. Ultimately, this process allows for seamless, high-performance visual morphing between different states of a web application.
