Color outline of the card

[schumi2309]

Goal

Hello,
I'd like to know how to draw just the outline of the card (the border) with a specific color, and how to adjust the line thickness.
Does anyone have a solution?
Thanks

Try this:

styles: |-
  .bubble-button-card-container {
    border-style: solid;
    border-width: 1px;
    border-color: rgb(...);
  }
