Thanks a lot @mirekmal … I also tried to use the layout card (I am also used to use for other dashboards as I have a wall tablet with obviously fixed width / height), but no success neither in the sense that I can not re-dimension the history cards to “stretch” in width and reduce their height, see the post I have made here : https://community.home-assistant.io/t/layout-card-take-control-of-where-your-cards-end-up/147805/932
If you might help in that topic related to the Layout-card … many Thanks !
