基本的な例

`font-sans` や `font-mono` のようなユーティリティを使用して、要素のフォントファミリーを設定します

font-sans

The quick brown fox jumps over the lazy dog.

font-serif

The quick brown fox jumps over the lazy dog.

font-mono

The quick brown fox jumps over the lazy dog.

<p class="font-sans ...">The quick brown fox ...</p>
<p class="font-serif ...">The quick brown fox ...</p>
<p class="font-mono ...">The quick brown fox ...</p>

カスタム値の使用

Use the font-[<value>] syntax to set thefont familybased on a completely custom value

<p class="font-[Open_Sans] ...">
Lorem ipsum dolor sit amet...
</p>

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

<p class="font-(family-name:--my-font) ...">
Lorem ipsum dolor sit amet...
</p>

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

テーマのカスタマイズ

Use the --font-* theme variables to customize thefont family utilities in your project

@theme {
--font-display: "Oswald", "sans-serif";
}

Now the font-display utility can be used in your markup

<div class="font-display">
<!-- ... -->
</div>

You can also provide default font-feature-settings and font-variation-settings values for a font family

@theme {
--font-display: "Oswald", "sans-serif";
--font-display--font-feature-settings: "cv02", "cv03", "cv04", "cv11";
--font-display--font-variation-settings: "opsz" 32;
}

If needed, use the @font-face at-rule to load custom fonts

@font-face {
font-family: Oswald;
font-style: normal;
font-weight: 200 700;
font-display: swap;
src: url("/fonts/Oswald.woff2") format("woff2");
}

If you're loading a font from a service like Google Fonts, make sure to put the @import at the very top of your CSS file

@import url("https://fonts.googleapis.com/css2?family=Roboto&display=swap");
@import "tailwindcss";
@theme {
--font-roboto: "Roboto", sans-serif;
}

Browsers require that @import statements come before any other rules, so URL imports need to be above imports like @import "tailwindcss" which are inlined in the compiled CSS.
