How do you create a tooltip in HTML?

The correct approach to create a tooltip in HTML is by using the title attribute. When you add the title attribute to an HTML element, such as a link or an image, it provides a small pop-up box that appears when the user hovers over that element. This feature is part of the HTML specification and is supported by all modern web browsers, making it a reliable way to display additional information.

For example, if you have an image tag like this: <img src="image.jpg" title="This is an image">, hovering over the image will show "This is an image" as a tooltip.

While other methods like using data-tooltip or creating a hover effect could also be utilized to display information, they typically require additional CSS or JavaScript code and are not standard features in plain HTML. The alt attribute, on the other hand, is used primarily for accessibility purposes and describes images for those who cannot see them, rather than serving as a tooltip.
