A tooltip is a graphical user interface (GUI) feature that provides additional information or context about a particular element when the user hovers their cursor over it or focuses on it using other input methods. It typically appears as a small box or pop-up near the element and disappears when the user moves their cursor away.
When using tooltips, it's essential to consider a few best practices. Keep the tooltip text concise, clear, and relevant. Avoid overwhelming users with excessive information. Ensure that tooltips don't obstruct or cover other critical elements on the screen. Additionally, tooltips should appear promptly when hovering over an element, and they should disappear when the cursor moves away to prevent interference with user interactions.
