When integrating Tippy.js into large or complex web projects, you may encounter some recurring issues that can affect tooltip visibility, positioning, and interactivity. Addressing these problems efficiently will help you maintain a smooth user experience and prevent frustrating bugs. Here is a list of frequent problems and practical strategies for debugging them:

• Tooltip appears in the wrong place: check if the reference element has unexpected margins, padding, or transforms applied; review the placement option in your Tippy.js configuration;
• Tooltip is hidden behind other elements: inspect the z-index property of both the tooltip and surrounding elements; ensure the tooltip's container is not clipped by an ancestor with overflow: hidden or similar;
• Tooltip does not show or close as expected: verify that event triggers (like mouseenter, focus, click) are correctly set; check for event propagation conflicts or JavaScript errors in the console;
• Tooltip content is incorrect or not updating: ensure dynamic content is properly passed to Tippy.js and that updates are triggered if content changes after initialization;
• Multiple tooltips overlap or stack incorrectly: manage instances carefully, and consider using the singleton or allowHTML options to control behavior;
• Tooltip styles are not applied: confirm that custom CSS selectors are correct and that there are no specificity issues or conflicting styles from other frameworks or libraries;
• Tooltip causes scrollbars or layout shifts: check for large content, improper max-width, or layout constraints, and adjust styling as needed.

By systematically inspecting these common trouble spots and using browser developer tools to debug CSS and JavaScript, you can resolve most issues efficiently.
