Tooltip

According to WikiPedia, the tooltip or infotip or a hint is a common graphical user interface element. It is used in conjunction with a cursor, usually a pointer. The user hovers the pointer over an item, without clicking it, and a tooltip may appear—a small "hover box" with information about the item being hovered over.

In Vuecidity, v-toltip is a directive, expecting an object, containing optional (default is top) position (top, right, bottom or left) and text of the tooltip.
