Probably because the code is wrong from the beginning.

  card-mod-root-yaml: |
    .: |   ----------- this !!!!
      app-header {
        display: none;
      }

At least these types of errors you may do:

  • wrong value is selected for a property (like “color: 12px”);
  • correct value for a property is not set - “!important” is needed;
  • wrong attribute is selected (like “colr: red”);
  • wrong element is selected;
  • wrong path is specified - so none element is selected;
  • smth else.

And use Code Inspector to check a possible reason.
