## Time Range Mode

The player supports a special time range mode for segmented playback:

```typescript
const player = new HLSPlayer(videoElement);

// Set time ranges
player.setTimeRanges([
  { start: 0, end: 300, url: 'video1.mp4' },
  { start: 600, end: 900, url: 'video2.mp4' },
  { start: 1200, end: 1500, url: 'video3.mp4' }
]);

// Load first segment
await player.load('video1.mp4');
```

In time range mode:
- Progress bar shows available segments
- Seeking automatically switches between segments
- Progress display shows relative time within segments

## Styling

The player comes with default styles that can be customized using CSS:

```css
.hls-player {
  /* Container styles */
}

.hls-player-video {
  /* Video element styles */
}

.hls-player-controls {
  /* Controls container styles */
}

.hls-player-progress {
  /* Progress bar styles */
}

.hls-player-rate {
  /* Playback rate controls styles */
}
```
