CSS Overscroll Behavior in Chrome

The source provides a comprehensive technical guide to the CSS overscroll-behavior properties, which allow web developers to control scroll chaining and boundary effects like pull-to-refresh or elastic rubber-banding. It details the three main values—auto, contain, and none—explaining how they affect both nested scrolling elements and the root viewport, distinguishing between stopping scroll propagation and suppressing visual overscroll feedback. A significant portion of the text is dedicated to explaining Chrome's implementation pipeline, outlining how the CSS properties are parsed by the Blink rendering engine, propagated to the compositor thread (the cc component) for efficient scroll handling, and finally interpreted by platform-specific code on Android and macOS to control native UI features. The text emphasizes that using this CSS property is the recommended, high-performance method for managing complex scrolling interactions in modern web applications and embedded content.
