Headline rhythm

Resize the window and every line scales in proportion.

The Problem

  • Hard breakpoints cause sudden jumps in readability.
  • Responsive type rules sprawl across multiple media queries.
  • Mixing semantic tags and utility sizes creates design drift.
  • Teams struggle to keep hierarchy consistent across pages.

The Solution

  • Smooth continuous scaling from 360px to desktop widescreen.
  • Semantic classes like .text-h2 on any element.
  • Six variables control your entire type system.
  • Pure CSS clamp-based logic with no runtime dependency.

Configuration Generator

Tune your viewport range, base sizes, and scale ratios. The preview updates immediately and generates copy-paste-ready CSS.

Presets

Minimum (mobile)
Smallest viewport width where fluid scaling starts (usually 320-390px).
Body font size at min viewport. Common range is 15-17px.
Scale ratio at min viewport. Lower ratios create subtler hierarchy.
Maximum (desktop)
Largest viewport where scaling stops. Wider screens stay at max sizes.
Body font size at max viewport. Typical desktop values: 17-20px.
Scale ratio at desktop. Higher values create more dramatic headings.

FAQ

Does this work in all modern browsers?

Yes. clamp(), custom properties, and modern selectors are widely supported in evergreen browsers.

Will this hurt performance?

No. This system is CSS-only and avoids runtime JavaScript for typography calculations.

Can I override only one heading size?

Yes. Override any variable or utility class while keeping the rest of the semantic scale.

How do I pick a ratio?

Start with 1.25 for balanced hierarchy, then increase for stronger contrast or reduce for denser UIs.

Can I use h2 styling on an h1 element?

Absolutely. Semantic utility classes are designed for exactly that level of flexibility.

What viewport range should I set?

A typical range is 360 to 1280. For larger displays, consider 320 to 1440 or 320 to 1920.

Does this replace Tailwind text-* utilities?

For type scale and semantics, yes. Keep Tailwind utilities for spacing, layout, and color.

Can I use it in Astro, React, and Vue?

Yes. The class names are framework-agnostic and work anywhere HTML classes are supported.
