Headless UI

Headless UI Overview

Headless UI is something you will reach for often in UI libraries. It keeps your workflow predictable and makes your intent obvious to reviewers and teammates.

When you learn headless ui properly, you avoid the guesswork that leads to mistakes and rework. The example below shows the shape you will use in most real UI libraries projects.

import * as Dialog from '@radix-ui/react-dialog';

function Modal() {
  return (
    <Dialog.Root>
      <Dialog.Trigger>Open</Dialog.Trigger>
      <Dialog.Portal>
        <Dialog.Overlay />
        <Dialog.Content>Hello</Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  );
}

Headless libraries provide accessible behaviour and leave all styling to you.

Headless UI Example

// install, import, and use a component
// npm install <library>
import { Button } from '<library>';

<Button variant="primary">Click me</Button>

• Start from a minimal Headless UI example and grow it only as needed.
• Keep things explicit so Headless UI behaves the same for everyone on the team.
• Name things clearly so teammates understand your Headless UI at a glance.
• Verify Headless UI works as expected before relying on it in important work.
