It is a special hover method to show extra text about the element when moved over it. When the mouse is hovered over that element, a tooltip dialogue box is displayed conveying the required information.

To implement a tooltip, let’s create some HTML text first.

Until the mouse hovers, the display is kept “hidden” and the rules of the tooltip text are written. The moment we hover, the visibility of the dialogue box is set to be true.

Output:

This way we can add a dialogue box on the elements to add accessibility to our website.

You can also experiment with the tooltip animation by including: CSS Transitions properties here.
