OH3 Standard height and shadow

Hi,

So I did an F12 / Inspect. Used Ctrl + Shift + C to select the default card. Filtered the applied styles for height, shadow and radius. Copied the styles from the default card and added to the styles of the custom widget.

component: f7-card
config:
  title: '=(props.item) ? "State of " + props.item : "Set props to test!"'
  footer: =props.prop1
  content: =items[props.item].displayState || items[props.item].state
  style:
    height: 120px
    border-radius: var(--f7-card-expandable-border-radius)
    box-shadow: var(--f7-card-expandable-box-shadow)
