Control the display and hide of child elements through:hover; 3. Use absolute positioning to set the prompt box position; 4. Add animation to improve the experience; 5. Pay attention to z-index and multi-directional adaptation. The specific implementation includes setting .tooltip as relative positioning, .tooltiptext is hidden by default, becomes visible when hover, and can add transition to achieve fading and delay effects.
