Tooltip

In common practice, the tooltip is displayed continuously as long as the user hovers over the element or the text box provided by the tool.

[1] Some smartphones have alternative input methods such as a stylus, which can show tooltips when hovering above the screen.

A common variant of tooltips, especially in older software, is displaying a description of the tool in a status bar.

[citation needed] Microsoft's tooltips feature found in its end-user documentation is named ScreenTips.

CSS, HTML, and JavaScript also other coding systems allow web designers to create customized tooltips.
