text-decoration-thickness

Utilities for controlling the thickness of text decorations.

Quick reference

Class	Styles
decoration-<number>	text-decoration-thickness: <number>px;
decoration-from-font	text-decoration-thickness: from-font;
decoration-auto	text-decoration-thickness: auto;
decoration-(length:<custom-property>)	text-decoration-thickness: var(<custom-property>);
decoration-[<value>]	text-decoration-thickness: <value>;

Examples

Basic example

Use utilities like decoration-1 and decoration-4 to control the thickness of text decorations:

<p class="underline decoration-1 ...">The quick brown fox...</p>
<p class="underline decoration-2 ...">The quick brown fox...</p>
<p class="underline decoration-4 ...">The quick brown fox...</p>

Using a custom value

Use the decoration-[<value>] syntax to set the text decoration thickness based on a completely custom value:

<p class="underline decoration-[0.25rem] ...">Lorem ipsum dolor sit amet...</p>

For CSS variables, you can also use the decoration-(length:<custom-property>) syntax:

<p class="underline decoration-(length:--my-thickness) ...">Lorem ipsum dolor sit amet...</p>

This is just a shorthand for decoration-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a text-decoration-thickness utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<p class="underline md:decoration-4 ...">Lorem ipsum dolor sit amet...</p>
