🙋 Introduction

The text-decoration-thickness property in CSS allows web developers to control the thickness of text decoration lines, such as underlines, overlines, and line-throughs.

This property provides more fine-grained control over the appearance of these decorations, allowing for better customization and design flexibility.

💡 Syntax

The syntax for the text-decoration-thickness property is straightforward. It can be applied to any text element, and you can specify the thickness using various units or keywords.

Syntax

Copied

element {
  text-decoration-thickness: value;
}

Here, value can be a length (e.g., 2px, 0.1em), a percentage, or a keyword.

🎛️ Default Value

The default value of the text-decoration-thickness property is auto, which means the thickness is determined by the browser and is typically based on the font size and type.

🏠 Property Values

auto	The browser determines the thickness.
from-font	Uses the thickness specified by the font (if supported).
length	Specifies the thickness using a length value (e.g., 2px, 0.1em).
percentage	Specifies the thickness as a percentage of the element's font size (e.g., 10%).
