JavaScript Responsive Handling
### Dual Player Elements
The JavaScript now handles both mobile and desktop player elements:
```javascript
// Cache both elements
DOM.playerTitle = document.getElementById('player-title'); // Mobile
DOM.playerTitleDesktop = document.getElementById('player-title-desktop'); // Desktop
// Update both simultaneously
function updateTrackInfo(track) {
// Mobile
if (DOM.playerTitle) DOM.playerTitle.textContent = track.title;
// Desktop
if (DOM.playerTitleDesktop) DOM.playerTitleDesktop.textContent = track.title;
}
// Update both play buttons
function updatePlayButton(isPlaying) {
// Desktop button
const icon = DOM.playBtn?.querySelector('i');
// Mobile button
const mobileIcon = DOM.mobilePlayBtn?.querySelector('i');
// Update both
}
```
### Event Listeners
Both mobile and desktop controls trigger the same functions:
```javascript
// Desktop play button
DOM.playBtn?.addEventListener('click', togglePlayPause);
// Mobile play button
DOM.mobilePlayBtn?.addEventListener('click', togglePlayPause);
// Both work seamlessly!
