1. A system for serving a digital form made up of a plurality of individual form fields on a computing appliance that has limited display space, the system comprising: a server connected to a network, the server comprising at least one hardware processor and a non-transitory physical storage medium; at least one computing appliance connected to the network, the computing appliance having a display with a graphical user interface (GUI) for at least one user; and program code stored on the non-transitory physical storage medium, the program code executable by the hardware processor to perform: determining whether the computing appliance has limited display space based on properties of the display and properties of the digital form; in response to determining that the computing appliance has limited display space, serving or displaying an unpopulated first form field of the plurality of individual form fields of the digital form; receiving a user input to populate the first form field; automatically determining whether the user input completely populates the first form field; in response to determining that the user input completely populates the first form field, determining whether all individual form fields of the digital form have been completely populated; and in response to determining that not all individual form fields of the digital form have been completely populated, automatically serving or displaying an unpopulated second form field of the plurality of individual form fields of the digital form, wherein the first form field is minimized or moved out of an original position to make room for the second form field, and wherein the second form field is displayed over a subset of the original position of the first form field.
