Introduction

CSS controls what happens when a box contains too much text or media. By default, content visibly spills out. Developers can hide this extra content or add scrollbars to keep the layout neat.

Example

1/* this adds a scrollbar */
2div {
3  width: 200px;
4  height: 100px;
5  overflow: scroll;
6}

Key Points

The `visible` value shows content outside the box.
The `hidden` value clips overflowing content completely.
The `scroll` value adds permanent scrollbars.
The `auto` value adds scrollbars only when needed.
