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 appearâa small "hover box" with information about the item being hovered over. tooltips do not appear on mobile operating systems, because there is no cursor.  ==variants== a common variant, especially in older software, is displaying a description of the tool in a status bar. another system, on old mac os versions, that aims to solve the same problem, but in a slightly different way, is balloon help. microsoft invented another term, "screentip", and uses it in its end-user documentation. ==examples== demonstrations of tooltip usage are prevalent on web pages. many graphical web browsers display the title attribute of an html element as a tooltip when a user hovers the pointer over that element; in such a browser you should be able to hover over wikipedia images and hyperlinks and see a tooltip appear. some browsers, notably microsoft's internet explorer (prior to version 7), will also display the alt attribute of an image as a tooltip in the same manner if an alt attribute is specified and a title attribute is not. this is an incorrect behaviour of the alt attribute according to the w3c specification. if a title attribute is also specified, it will override the alt attribute for tooltip content. css, html, and javascript allow web designers to create customized to ==name== the term tooltip originally came from older microsoft applications (like microsoft word 95), which had a toolbar where moving the mouse over the buttons (the toolbar icons) displayed these tooltips, a short description of the function of the tool in the toolbar. more recently, these tooltips are used in various parts of an interface, not only on toolbars. ==hiding tooltips== some software and applications, such as gimp, provide an option for users to turn off some or all tooltips. however, such options are left to the discretion of the developer, and are often not implemented. ==see also== *status bar *mouseover ==references==
