An accessible media player provides keyboard controls, screen reader announcements, caption support, and customizable playback options.

## What You'll Learn

The key accessibility features every media player needs and how to implement them.

## Why It Matters

The native HTML5 video player has basic accessibility, but custom players often break keyboard support and lack screen reader announcements.

## Real-World Use

A user with a motor disability uses a keyboard to control video playback. Space toggles play/pause. Arrow keys seek. M toggles mute. The player announces state changes via aria-live.

## Accessible Player

```html
<div role="region" aria-label="Video player">
  <video id="player" controls>
    <source src="tutorial.mp4" type="video/mp4">
    <track kind="captions" src="captions.vtt" default>
  </video>

  <!-- Custom controls must be keyboard accessible -->
  <div role="toolbar" aria-label="Video controls">
    <button aria-label="Play" onclick="togglePlay()">Play</button>
    <button aria-label="Mute" onclick="toggleMute()">Mute</button>
    <input type="range" aria-label="Volume" min="0" max="1" step="0.1">
    <button aria-label="Full screen" onclick="toggleFullscreen()">Full</button>
  </div>
</div>

Keyboard Shortcuts

document.addEventListener('keydown', function(e) {
  if (e.target.closest('[role=region]')) {
    switch(e.key) {
      case ' ':
      case 'k':
        e.preventDefault();
        togglePlay();
        break;
      case 'm':
        toggleMute();
        break;
      case 'f':
        toggleFullscreen();
        break;
      case 'ArrowLeft':
        video.currentTime -= 10;
        break;
      case 'ArrowRight':
        video.currentTime += 10;
        break;
    }
  }
});

Common Mistakes

1. Custom controls are not keyboard accessible

Custom play, mute, and fullscreen buttons must be focusable and operable via keyboard.

2. No aria-label on icon-only buttons

Buttons with only icons need aria-label to describe their function.

3. No focus indicator on controls

All player controls must have visible focus indicators.

4. Volume slider not keyboard accessible

Range inputs need keyboard support (arrow keys) by default, but ensure they are focusable.

5. Screen reader announcements missing

Use aria-live regions to announce play/pause, mute/unmute, and progress changes.

Practice Questions

1. What keyboard key toggles play/pause in most players? Space bar or the K key.

2. What attribute labels icon-only player buttons? aria-label on the button element describes its function.

3. What role should the player controls container have? role="toolbar" or role="group" with an appropriate aria-label.

Challenge: Build a minimal accessible video player with keyboard shortcuts (Space, M, F, Arrow keys) and aria-live announcements.
