Mushroom Cards - Build a beautiful dashboard easily 🍄 (Part 2)

i found a post a while ago that helped me with the card-mod code blocks.
it might work like this:

      style: 
        mushroom-shape-icon$: |
          .shape {
            margin-right: 50px;
          }
        .: |
        ha-card {
          background: rgba(var(--rgb-primary-background-color), 0.3);
          left: -20px;
          top: -20px;
          width: 500px;
          --spacing: 10px 10px 0px 12px;
          --icon-size: 70px;
          --ha-card-border-width: 0;
          --chip-box-shadow: none;
        }
