Tooltips are small, informative pop-up boxes that appear when a user hovers over an element on a website or application. They provide additional context or explanations about the item, such as buttons, icons, or links, helping users understand their functions without cluttering the interface. Tooltips enhance user experience by offering guidance without requiring extra clicks. Typically, tooltips contain brief text and may include icons or images for clarity. They are commonly used in user interfaces, such as websites, software applications, and mobile apps, to improve usability and accessibility. By offering instant information, tooltips help users navigate and interact more effectively.
