CSS Ink Overflow: Definition, Effects, and Clipping

The provided text offers a comprehensive technical exploration of ink overflow in CSS, distinguishing it from scrollable overflow. Ink overflow is defined as purely decorative or visual effects—like shadows, outlines, and glows—that render outside an element’s box but do not affect document layout, scrolling metrics, or interactivity. In contrast, scrollable overflow is actual content that exceeds the container and may necessitate scrollbars. The source details how various CSS properties, such as overflow: hidden and contain: paint, clip ink overflow, while newer features like overflow-clip-margin allow visual effects to escape clipping boundaries. Furthermore, the text examines implementation specifics within major browser engines like Blink (Chromium) and discusses the historical motivations for standardizing this concept to ensure visual effects do not cause layout instability or unintended scrollbars.
