ptg 386 Chapter 16 With the spry tooltip widget, you can add screen information for ele- ments on a web page. When you hover over an element, a tooltip with information about the element, a title or short description, appears for a short period of time or until you stop hovering over the element. A spry tooltip consists of a container, page element, and JavaScript. When you insert a spry tooltip, a container appears with a blue tab on top and a placeholder sentence inside.
