OK, so here is sample code you can use (dashboard in Panel mode, as @dextar described in post above):
type: custom:layout-card
layout_type: custom:grid-layout
layout_options:
grid-template-columns: 10% 80% 10%
grid-template-rows: auto
grid-template-areas: |
"left middle right"
cards:
- type: custom:gap-card
view_layout:
grid:area: left
# here your actual card(s) goes
- type: entities
entities:
- entity: light.attic_stairwais_light
- entity: light.basement
view_layout:
grid:area: middle
- type: custom:gap-card
view_layout:
grid:area: righ
Resylt loos like that:
