pm me the details what you have

#

This is something that should work by default

#

type: button
icon: mdi:alpha-a-circle
icon_height: 64px
show_name: true
show_icon: true
card_mod:
  style: |
    /* For most column based layouts (Masonry and Sidebar) */
    /* Layout Cards custom layouts will work, */
    /* but may require tweaking if default margins/paddings are changed */
    :host { height:calc(80vh - var(--header-height) - 16px); display: block; } }

    /* This value stays at 100% */
    /* Some card types may require additional tweaks.. */
    ha-card { height: 100%; }

    /* Default HA breakpoint for "mobile" layout */
    @media (max-width: 870px) {
     :host { height:calc(100vh - var(--header-height) - 16px); }
    }
