Hover transitions not working often happen when a hidden element with a higher z-index and "visibility: hidden" is layered above another interactive element. Even though it's not visible, it can block pointer events.
1. Understand the Problem
- Visibility: hidden means the element is not shown, but it still takes up space and can block interactions.
- If this element has a higher z-index, it sits above the element you’re trying to hover over.
- The non-visible element may intercept pointer events, preventing hover states from triggering underneath.
2. Use "Display: None" Instead
- Set the upper-layer element to Display: None instead of Visibility: Hidden when it shouldn’t be visible.
- Display: None removes it from the layout and interaction stack entirely, so it won’t block hover events behind it.
3. Adjust Z-Index or Positioning
- If hiding the element with display settings isn’t an option:
- Lower the z-index of the hidden element so it sits behind the interactive element.
- Alternatively, set its position to static to avoid stacking context if z-index stacking isn’t crucial.
4. Disable Pointer Events
- Apply pointer-events: none to the hidden element.
- This ensures the element can’t intercept mouse events even if it sits on top.
5. Check Hidden Element's Children
- Ensure that any child elements of the hidden container don’t independently retain pointer-events if the parent is not set to "pointer-events: none".
Summary
If hover transitions aren't firing due to an overlapping hidden element, fix it by using "display: none", adjusting z-index, or applying pointer-events: none to ensure it doesn’t block interaction.
