# ui.null

Function: | ui.null | (width=0, height=0, **properties):

This widget displays nothing on the screen. Why would one want to do this? If a widget requires contents, but you don't have any contents to provide it. It can also be used to create empty space, by giving non-zero width and heigh arguments.

## Example

    python:
        # Stats Window
        ui.frame(xpos=0,
                 ypos=0,
                 xanchor='left',
                 yanchor='top',
                 xfill=True,
                 )

        ui.vbox()

        ui.text('Statistics')
        ui.null(height=20)

        for name, range, value in stats:
            ui.hbox()
            ui.text(name, minwidth=150)
            ui.bar(range, value, ypos=0.5, yanchor='center')
            ui.close() # for the ui.hbox

        ui.close() # for the ui.vbox
