Difference between overflow: clip and overflow: hidden in CSS Level 4
Both overflow: clip and overflow: hidden visually hide content that exceeds an element’s box, but they behave differently in how they handle scrolling, clipping, and layout interactions. The clip value was introduced in CSS Overflow Module Level 4 to provide a more precise clipping mechanism.
overflow: hidden hides overflowing content but still establishes a scroll container, allowing programmatic scrolling using JavaScript (e.g., scrollTop, scrollTo).
overflow: clip hides overflowing content without creating a scroll container, so scrolling (even via script) is completely disabled.
clip defines a strict visual clip to the element’s border box, offering predictable clipping behavior without scroll offsets.
hidden may still reserve space for scrollbars in some contexts, while clip never does.
