Tooltips provide contextual information on hover without cluttering the interface, improving user experience with helpful hints and descriptions. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented tooltip systems in Vue applications throughout my 11 years of Vue development. The most maintainable approach is creating a reusable tooltip component with Composition API and conditional rendering on hover. This method ensures consistent tooltip behavior across the application with minimal code duplication.

Creating tooltips enhances user experience by providing contextual information on hover or focus without cluttering the interface. As the creator of CoreUI with over 25 years of development experience, I’ve implemented tooltip systems across numerous production applications. The most effective approach is using React state with mouse and focus event handlers to control tooltip visibility and positioning. This provides accessible, responsive tooltips that work with both mouse and keyboard navigation.
