Changing Title Margin and Size

Hello!

I am trying to remove the margin between the title of my to do list card and the first task

type: todo-list
entity: todo.dan_s_long_term_task_for_the_week
title: Dan's List
card_mod:
  style:
    .: |
      ha-card.type-todo-list div.header {
        display: none;
      }
      ha-card.type-todo-list div.divider {
        display: none;
      }
      ha-card.type-todo-list .addRow {
        display: none;
      }
      ha-check-list-item.editRow.completed {
        display: none;
      }

Any help would be appreciated!

Thanks in advance
