Removing empty space around two components in a dbc.Card

I have the code below. I am having a hard time understanding how to control empty space around daq.Guage object and how to center the indicator in that column. My code is below, any help would be appreciated. I am using the bootstrap SUPERHERO theme.

   dbc.Col([dbc.Card(
                    [
                        dbc.Row(
                            [
                             dbc.Col(
                                    daq.Gauge(
                                            showCurrentValue=False,
                                            #units="tweets per day",
                                            color={"gradient":True,"ranges":{'#5CB85C':[0,0.5],'#FFC107':[0.5,0.75],'#D9534F':[0.75,1]}},
                                            value=0.90,
                                            label='TBD',
