To enhance user interfaces, you can embed custom HTML, images, and even dynamic content inside Tippy.js popovers. This approach allows you to present rich, interactive elements such as cards, forms, or media within floating UI elements. When embedding complex content, think about the structure: use semantic HTML for accessibility, and ensure that images are optimized for quick loading. Dynamic content—such as updating information or interactive widgets—can make popovers feel like mini-applications. However, you must be mindful of performance. Heavy scripts or frequent DOM updates inside a popover can slow down your application or cause lag, especially if many popovers are open at once. Always keep the popover content as lightweight as possible, and load external resources only when needed. This balance ensures that your popovers remain fast and responsive while providing a rich user experience.
