Q: What is the purpose of overflow: visible?

`overflow: visible` is the default value for the `overflow` property. It allows content that exceeds the dimensions of a container to **overflow and be fully visible** outside the container. `overflow: visible;` – Excess content is not clipped and can spill outside the container. No scrollbars are added, even if the content overflows. Useful when you want overflowing content to remain visible, such as decorative elements or tooltips. div.visible { width: 200px; height: 100px; border: 1px solid black; overflow: visible; } This content exceeds the container's height, but it is fully visible outside the box.
