Working with Slider Positioning ​

Automatic Positioning ​

The slider intelligently positions itself:

  • Checks viewport boundaries
  • Switches direction if needed
  • Maintains usability on all devices
  • Adapts to scroll position

Direction Behavior ​

Desktop Behavior:

  • Respects your chosen direction
  • Smooth hover interactions
  • Keyboard navigation support

Mobile Behavior:

  • Touch to show slider
  • May override direction for space
  • Tap outside to hide
  • Optimized for one-handed use

Positioning Tips ​

  1. Up Direction: Best for bottom-positioned players
  2. Down Direction: Ideal for headers or top bars
  3. Left/Right: Good for vertical layouts
  4. Auto-adjustment: Trust the intelligent positioning

Best Practices ​

Accessibility ​

  1. Keyboard Navigation

    • Space/Enter to mute/unmute
    • Arrow keys adjust volume when focused
  2. Screen Readers

    • Volume level announced
    • Mute state communicated
  3. Touch Targets
    • Minimum 44x44px touch area
    • Adequate spacing from other controls
    • Clear visual feedback

Responsive Design ​

.wp-block-podcaster-plus-volume {
  --pp-volume-color-background-desktop: #f0f0f0;
  --pp-volume-color-icon-desktop: #333;
}

/* Larger mobile touch target */
@media (max-width: 767px) {
  .wp-block-podcaster-plus-volume {
    --icon-size: 36px;
    padding: 8px;
  }
}

/* Always visible slider */

  opacity: 1 !important;
  visibility: visible !important;
}
