Then add it to your interface:

import { ClassicTyping } from "@/components/ui/classic-typing"

<ClassicTyping size={48} speed={1.6} />

Inherits text color. Accepts className, style, and a custom loading label. Respects reduced-motion preferences.

import type { CSSProperties, ComponentProps } from "react"

export type ClassicTypingProps = ComponentProps<"span"> & {
  size?: number
  /** Duration of one complete cycle, in seconds. */
  speed?: number
  label?: string
}

export function ClassicTyping({
  size = 40,
  speed = 1.6,
  label = "Loading",
  className,
  style,
  ...props
}: ClassicTypingProps) {
  return (
    <span
      role="status"
      aria-label={label}
      {...props}
      className={["classic-typing-loader", className].filter(Boolean).join(" ")}
      style={
        {
          width: size,
          height: size,
          "--loader-size": `${size}px`,
          "--loader-duration": `${Math.max(0.1, speed)}s`,
          ...style,
        } as CSSProperties
      }
    >
      <span aria-hidden="true" className="classic-typing-loader-body">
        {[0, 1, 2].map((i) => (
          <span
            key={i}
            className="classic-typing-loader-dot"
            style={{

              animationDelay: `${(i / 6 - 1) * Math.max(0.1, speed)}s`,
            }}
          />
        ))}
      </span>
      <style>{`
