MaskLine
The Mizu headline reveal — text rises from inside its own mask, one line at a time.
Live — this one is real
Movement
travels.
Usage
import { MaskLine } from "mizu-ui";
export function Headline() {
return (
<h1 style={{ margin: 0, fontSize: 64, fontWeight: 900, lineHeight: 1 }}>
<MaskLine>Movement</MaskLine>
<MaskLine delay={0.15}>travels.</MaskLine>
</h1>
);
}
Source & setup
Add this component to your project with the shadcn CLI. The command copies its source into your configured UI directory, with base.css, Mizu’s tokens, and the stylesheets that hold its rules. Each rule lives in one stylesheet, so components you add together never repeat CSS. In a project without a components.json, run npx shadcn@latest init 0xuser64bit/mizu/preset first: plain init installs shadcn’s theme into your global CSS. Then load the fonts.
npx shadcn@latest add 0xuser64bit/mizu/mask-lineEvery component imports from its own path, its name in kebab case. To paste the example, replace its mizu-ui import with:
import { MaskLine } from "@/components/ui/mizu/mask-line";For npm imports, import mizu-ui/styles.css once. Fonts are optional via mizu-ui/fonts.css. Override --mizu-* tokens or use className for local styling. Requires React and Motion. A Client Component: its source starts with “use client”.
Inspect motion/MaskLine.tsx
Source is included in the npm package under src/motion/MaskLine.tsx.

Accessibility
Text remains in the document — the mask is pure CSS overflow. Screen readers see the full headline immediately.
Motion
1.15s expo rise per line. Stagger delays for multi-line headlines.
