The Show-Hide Elements behavior shows, hides, or restores the default visibility of one or more page elements. This behavior is useful for displaying information as the user interacts with the page. For example, as the user moves the pointer over an image of a plant, you could show a page element giving details about the plant’s growing season and region, how much sun it needs, how large it can grow, and so on. The behavior only shows or hides the pertinent element—it does not actually remove the element from the flow of the page when it is hidden.
