Use text scale tokens, font utilities, line height, letter spacing, families, and weights.

Future-proof infrastructure

From typography to spacing, every detail is intentionally designed to provide visual harmony, adaptability, and intuitive customization across your entire site.

Typography tokens define readable type scale, line height, letter spacing, font families, and font weights. Use text:<size> when you want a complete type treatment, and use lower-level typography utilities when you need to tune one property.

<p class="text:lg font:medium">Readable product copy</p>

@layer theme {    :root {        --font-size-lg: 1.125rem;        --font-weight-medium: 500    }}@layer utilities {    .text\:lg {        font-size: var(--font-size-lg);        line-height: max(1.8em - max(0rem, var(--font-size-lg) - 1rem) * 1.12, var(--font-size-lg));        letter-spacing: clamp(-.072em, calc((var(--font-size-lg) - 1rem) * -.048), 0em)    }    .font\:medium {        font-weight: var(--font-weight-medium)    }}

Namespaces for typography

Typography is built from theme tokens organized into focused namespaces.

Utilities search the relevant namespace, so font:lg, leading:md, and tracking:tight can use short token names without the full custom property prefix.

All-in-one text scale

At its core, the system is powered by a semantic type scale from text:3xs to text:10xl. These values are calibrated as complete text treatments, not just mathematically scaled font sizes.

Use text:<size> to apply the tuned font size, line height, and letter spacing with one class.

• text:3xs ~ text:xs — For fine print, annotations, captions, or table labels
• text:sm ~ text:lg — Standard text sizes for body copy, paragraphs, and buttons
• text:xl ~ text:3xl — Ideal for subheadings, lead paragraphs, or callouts
• text:4xl ~ text:10xl — Reserved for large headings, page titles, and hero sections

Use font:<size> when you only want the font-size token. Use leading:* and tracking:* when the design intentionally adjusts line height or letter spacing separately.

Body text

Use tokens like text:sm, text:md, and text:lg to style body text, descriptions, and paragraphs.

<p class="text:sm">Design is not just about aesthetics—it’s...</p><p class="text:md">Design is not just about aesthetics—it’s...</p><p class="text:lg">Design is not just about aesthetics—it’s...</p>

Headings

Use tokens like text:lg, text:xl, and text:2xl to style article headings.

<h2 class="text:2xl">Design is not just about aesthetics—it’s...</h2><h3 class="text:xl">Design is not just about aesthetics—it’s...</h3><h4 class="text:lg">Design is not just about aesthetics—it’s...</h4>

Page titles

Use tokens like text:3xl and text:4xl to style page titles and hero sections.

<h1 class="text:4xl">Designing for clarity and consistency...</h1><h1 class="text:3xl">Designing for clarity and consistency...</h1>

Without vs with text:<size>

Manually configuring typography often requires juggling font-size, line-height, and letter-spacing. This becomes inconsistent when the same heading or paragraph style appears across components.

The type treatment is assembled manually.

<h1 class="font:3xl tracking:-0.048em leading:2.4rem">...</h1>

The type treatment uses the shared text scale.

<h1 class="text:3xl">...</h1>

The text:3xl token applies a finely tuned combination:

@layer theme {    :root {        --font-size-3xl: 2rem    }}@layer utilities {    .text\:3xl {        font-size: var(--font-size-3xl);        line-height: max(1.8em - max(0rem, var(--font-size-3xl) - 1rem) * 1.12, var(--font-size-3xl));        letter-spacing: clamp(-.072em, calc((var(--font-size-3xl) - 1rem) * -.048), 0em)    }}

Prefer text:<size> for repeated body, heading, and display styles. Reach for lower-level typography utilities only when the design intentionally departs from the text scale.

Type scale

The font scale ranges from font:3xs to font:10xl, with each size intentionally designed to deliver visual harmony and clear hierarchy across a variety of use cases.

Use font size tokens like font:xs, font:sm, and font:md to set the font size of an element.

<div class="font:xs">Sphinx of black quartz, judge my vow.</div><div class="font:sm">Sphinx of black quartz, judge my vow.</div><div class="font:md">Sphinx of black quartz, judge my vow.</div><div class="font:lg">Sphinx of black quartz, judge my vow.</div><div class="font:xl">Sphinx of black quartz, judge my vow.</div><div class="font:2xl">Sphinx of black quartz, judge my vow.</div>

Font families

Use tokens like font:sans, font:serif and font:mono to set font families for elements.

<p class="font:sans">Heavy boxes perform quick waltzes and jigs.</p><p class="font:serif">Heavy boxes perform quick waltzes and jigs.</p><p class="font:mono">Heavy boxes perform quick waltzes and jigs.</p>

See the font family reference for more details on how to add custom fonts.

Font weights

Our typography system defines a semantic range of font weight tokens, from font:thin to font:heavy, providing clear naming for visual emphasis and typographic hierarchy.

• font:thin extra-light strokes for subtle or elegant UI elements
• font:line light weight, ideal for large headings or minimalist design
• font:regular default weight for body text and general readability
• font:medium slightly bolder for subheadings or emphasis
• font:bold strong emphasis, often used in call-to-action or UI labels
• font:heavy maximum weight for impact, branding, or visual anchors

Use tokens like font:thin, font:regular, and font:bold to set the font weight of an element.

<div class="font:thin">Elegant forms shape visual harmony.</div><div class="font:extralight">Elegant forms shape visual harmony.</div><div class="font:regular">Elegant forms shape visual harmony.</div><div class="font:medium">Elegant forms shape visual harmony.</div><div class="font:semibold">Elegant forms shape visual harmony.</div><div class="font:bold">Elegant forms shape visual harmony.</div><div class="font:extrabold">Elegant forms shape visual harmony.</div><div class="font:heavy">Elegant forms shape visual harmony.</div>

Line height

Use the predefined line height tokens like leading:xs, leading:sm, and leading:lg to set the line height of an element.

<div class="leading:xs">Design is not just about aesthetics—it’s...</div><div class="leading:sm">Design is not just about aesthetics—it’s...</div><div class="leading:md">Design is not just about aesthetics—it’s...</div><div class="leading:lg">Design is not just about aesthetics—it’s...</div><div class="leading:xl">Design is not just about aesthetics—it’s...</div>

Letter spacing

Use tokens like tracking:tight and tracking:wider to set letter spacing.

<div class="tracking:tightest">LETTERS ALIGN WITH PERFECT RHYTHM</div><div class="tracking:tighter">LETTERS ALIGN WITH PERFECT RHYTHM</div><div class="tracking:tight">LETTERS ALIGN WITH PERFECT RHYTHM</div><div class="tracking:normal">LETTERS ALIGN WITH PERFECT RHYTHM</div><div class="tracking:wide">LETTERS ALIGN WITH PERFECT RHYTHM</div><div class="tracking:wider">LETTERS ALIGN WITH PERFECT RHYTHM</div><div class="tracking:widest">LETTERS ALIGN WITH PERFECT RHYTHM</div>
