CSS Overflow Wrap Property

The CSS Overflow Wrap property is an essential tool for web developers, enabling them to control how text behaves when it exceeds the width of its container. This article will provide a comprehensive understanding of the overflow-wrap property, its importance, related properties, and practical examples to illustrate its usage.

In web design, it is crucial that content is readable on various screen sizes. Without proper text wrapping, users may encounter text that spills over the edges of containers, resulting in a poor user experience. The overflow-wrap property enhances text readability by controlling line breaks intelligently.
