Text box
A text box, also called an input box, text field or text entry box, is a control element of a graphical user interface (GUI) that allows users to enter text for processing by a program.
A typical text box is a rectangle, possibly with a border that separates the text box from the rest of the interface. Text boxes may contain horizontal and vertical scrollbars. Text boxes usually display a text cursor (commonly a blinking vertical line), 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.
