text-decoration-thickness

Examples

Basic example

Use decoration-<number> utilities like decoration-2 and decoration-4 to change the text decoration thickness of an element:

<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="decoration-[0.25rem] ...">  <!-- ... --></p>

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

<p class="decoration-(--my-decoration-thickness) ...">  <!-- ... --></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 ...">  <!-- ... --></p>
