Sharepoint list how to wrap text in gallery view

uttam27 thanks for the hint - Unfortunately all this does, is to take the bold typeface from the header, where this "class" attribute is set.

As a reference, here's the relevant <div> from my JSON formatting - The incorrect breaks are happening in the "Beschreibung".

{
  "elmType": "div",
  "attributes": {
    "class": "sp-card-displayColumnContainer"
  },
  "children": [
    {
      "elmType": "p",
      "attributes": {
        "class": "ms-fontColor-neutralSecondary sp-card-label"
      },
      "txtContent": "Projekt:"
    },
    {
      "elmType": "p",
      "style": {
        "text-align": "justify",
        "height": "150px",
        "white-space": "break-word"
      },
      "attributes": {
        "title": "[$Beschreibung]",
        "class": "ms-fontColor-neutralPrimary "
      },
      "txtContent": "=if ([$Beschreibung] == '', '–', [$Beschreibung])"
    }
  ]
}
