Q: What is the overflow property in CSS? Why is the overflow property used?

The `overflow` property in CSS controls how content that exceeds the size of its container is handled. It is commonly used to prevent content from spilling outside an element's box and to manage scroll behavior. `overflow: visible;` – Default. Content spills outside the container without clipping. `overflow: hidden;` – Hides any content that exceeds the container's bounds. `overflow: scroll;` – Always shows scrollbars, allowing users to scroll overflowing content. `overflow: auto;` – Adds scrollbars only if the content overflows. Used to create scrollable sections, prevent layout breaks, and improve visual consistency. div.container { width: 200px; height: 100px; border: 1px solid black; overflow: auto; } This is some long content that will overflow the container if it is too big. Scrollbars will appear if necessary.
