What happens when you set overflow: hidden on a container with overflowing child content?

• A. It clips the content that overflows.
• B. It hides overflow but allows scrollbars to appear.
• C. It expands the container to fit content.
• D. It shows scrollbars always.

Answer: (A)

Overflow clipping happens. When you apply overflow: hidden to a container, the browser defines a clipping region that matches the element’s content box. Any child content that extends outside that region is not drawn, effectively cutting it off. The element’s size doesn’t grow to fit the overflowing content, and you won’t get scrollbars—the extra content is simply hidden. This is different from overflow: visible (which shows the overflow) and overflow: auto/scroll (which add scrollbars when needed).
