A text box is a common element of graphical user interface of computer programs, as well as the corresponding type of widget used when programming GUIs. A text box's purpose is to allow the user to input text information to be used by the program.
A typical text box is a rectangle of any size, possibly with a border that separates the text box from the rest of the interface. Text boxes may contain zero, one, or two scrollbars. Some text boxes may display a blinking vertical line (known as a caret), indicating the current region of text being edited. It is common for the mouse cursor to change its shape when it hovers over a text box.
An example of a text box is used in the Go/Search feature on every page of Wikipedia.
