Introduction

Font family utilities let you quickly change the style of text by choosing different fonts. This helps make your website look nice and easy to read.

When you want to make headings stand out with a special font.
When you need body text to be easy to read on all devices.
When you want to match your website's style with a brand font.
When you want to quickly test different fonts without writing custom CSS.
Syntax
Tailwind
font-sans
font-serif
font-mono

These classes apply different font families: font-sans for sans-serif fonts, font-serif for serif fonts, and font-mono for monospace fonts.

You add these classes to your HTML elements to change their font style.

Examples
This applies a clean, modern font without little strokes on letters.
Tailwind
<p class="font-sans">This text uses a sans-serif font.</p>
This font has small lines at the ends of letters, giving a classic look.
Tailwind
<h1 class="font-serif">This heading uses a serif font.</h1>
Monospace fonts have letters that take up the same space, good for code.
Tailwind
<code class="font-mono">Code looks like this with monospace font.</code>
Sample Program

This example shows three text blocks each using a different font family utility from Tailwind CSS. The heading uses serif, the paragraph uses sans-serif, and the code block uses monospace.
