CSS text-decoration Property: A Comprehensive Guide

The CSS text-decoration property is used to add decorative lines to text. You can specify the type, color, and style of the decoration, allowing for a variety of effects such as underlines, overlines, and line-throughs. This guide provides a detailed overview of the text-decoration property, including its syntax, values, and practical examples.

What is the text-decoration Property?

Using text-decoration, you can control the appearance of these decorations with a single declaration, making your CSS more concise and readable.
