Card Mod Help

Using the brilliant card mod to make a couple of things work but hit a wall on how to set some padding items on the alarm panel

Currently I have this:

        style:
          '#keypad mwc-button':
            $: |
              :host {
                padding: 4px !important;
              }
              button {
                font-size: 16px !important;
              }

And that works perfectly but I also want to reduce the padding around the Alarm text header

h1.card-header
padding-top: 12px;
padding-bottom: 16px;

armActions.actions
padding-top: 20px;

These seem to be what I need to change but I’ve tried many things and just can’t get these to adjust

Can someone please help with the coding to get this working?
