Skeleton.

A familiar shape while content arrives.

In practice

Set width and height to match the future content. Hidden from assistive technology. Motion respects reduced-motion preferences.

Installation

Install Coal once. Components and TypeScript declarations are included. React 19 and React DOM 19 are peer dependencies.

npm install http://localhost:3100/downloads/chlohal-coal-ui-0.5.0.tgz

This installs the local package. It is not yet published on npm. See installation for stylesheet setup and integration.

Usage

"use client";
import * as React from "react";
import "@chlohal/coal-ui/styles.css";
import { Skeleton } from "@chlohal/coal-ui";
export default function Example() {
    return (<div>
          <Skeleton />
          <div>
            <Skeleton />
            <Skeleton />
          </div>
        </div>);
}

Source

The original Coal implementation. Use the package export to integrate it.

import * as React from "react";
import { cn } from "./internal.js";
export type SkeletonProps = React.ComponentPropsWithRef<"div">;
export function Skeleton({ className, ...props }: SkeletonProps) {
  return (
    <div
      aria-hidden="true"
      className={cn("coal-skeleton", className)}
      {...props}
    />
  );
}

Accessibility checklist

• Provide an accessible name for controls, including icon-only buttons.
• Check keyboard navigation, visible focus and disabled states in your application.
• Do not rely on color alone to communicate status.
