Installation

pnpm dlx shadcn@latest add @magicui/line-shadow-text

Requires @magicui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { LineShadowText } from "@/components/ui/line-shadow-text"export function Example() {  return <LineShadowText shadowColor="#7c3aed">Explore the collection</LineShadowText>}
  • Use for animated hero headings, promotional labels, and attention-grabbing display text.
  • Use when a lightweight CSS-driven text effect is preferred over a full gradient or particle animation.
  • Use for decorative titles where the text itself remains selectable and present in the document.
  • Avoid using it for essential body copy or when users may be sensitive to continuous motion without adding motion controls externally.

Examples

Hero heading

A large animated heading using an h1 element and a brand-colored shadow.

hero-heading.tsx
import { LineShadowText } from "@/components/ui/line-shadow-text"export function HeroHeading() {  return (    <LineShadowText as="h1" className="text-5xl font-bold tracking-tight" shadowColor="#8b5cf6">      Build boldly    </LineShadowText>  )}

Promotional label

A compact animated label for a featured product or campaign.

promotional-label.tsx
import { LineShadowText } from "@/components/ui/line-shadow-text"export function FeaturedLabel() {  return (    <LineShadowText as="span" className="text-sm font-semibold uppercase" shadowColor="#f97316">      Limited release    </LineShadowText>  )}

Motion interaction

A paragraph element with a Motion hover animation.

motion-interaction.tsx
import { LineShadowText } from "@/components/ui/line-shadow-text"export function AnimatedMessage() {  return (    <LineShadowText      as="p"      className="text-lg font-medium"      whileHover={{ scale: 1.04 }}      transition={{ type: "spring", stiffness: 300 }}    >      Designed for momentum    </LineShadowText>  )}

API reference

PropTypeDefaultDescription
childrenstringnullRequired text content. The same string is rendered as the element content and supplied to the pseudo-element through `data-text`.
shadowColorstring"black"Color assigned to the `--shadow-color` CSS custom property used by the animated line shadow.
as"article" | "div" | "h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "li" | "p" | "section" | "span""span"Selects the rendered Motion element from the supported element set.
classNamestringnullAdditional classes merged with the component's built-in classes using `cn`.
MotionProps and HTML attributesMotionProps & Omit<React.HTMLAttributes<HTMLElement>, keyof MotionProps>nullAll compatible Motion props and non-overlapping React HTML attributes are forwarded to the rendered Motion element, including animation, event, accessibility, and standard element attributes.

Accessibility

  • The default rendered element is a `span`; use `as="h1"` through `as="h6"`, `p`, `li`, or another supported element to preserve appropriate document semantics.
  • The visible text is rendered as real child text, so it remains available to assistive technologies and text selection; `data-text` supports the decorative pseudo-element.
  • Choose a shadow color with sufficient contrast for the background and text treatment.
  • The component continuously animates with no built-in reduced-motion behavior. Respect user motion preferences at the surrounding application level when needed.
  • Because `children` is required to be a string, it does not accept nested markup or custom inline labels.
