⚡ Quick Fix (TL;DR)

The Culprit: N/A – this is a deliberate style choice, not something to fix.

The Fix: Set a value between 0 and 1 to make the element partially see-through. Lower values are more transparent, higher values are closer to fully visible.

.my-element {
  opacity: 0.7; /* move closer to 1 for more visible, closer to 0 for more transparent */
}
