Edit box highlights with blue border to show there are unsaved changes.
The depict helper text is shown when any statements are present in the user interface (note: "depict helper text" explains that the flag icon marks prominent)

Method:

1. to show the "depict helper text" the class .d-block needs adding to .prom-help. Should be removed if all depicts are deleted.
2. to highlight the border of the edit box that is actively being edited we need .active adding to the .edit-box that is being edited. (should happen at the same time as we activate/deactivate the save/cancel buttons)
