How to use this with ReactJS?

[EngineeredTruth]

I required my style sheet at the top, which is being compiled by webpack

require('./searchResults.scss');

which contains:

.labels {
  color: white;
  font-family: 'Roboto'
}

Created a new marker:
createMarker(lat, lng) {

    var marker = new google.maps.LatLng(
      lat, lng
    );

    return new MarkerWithLabel({
      position: marker,
      map: this.map,
      icon: this.state.icon,
      labelContent: '14'
      labelClass: "labels", // the CSS class for the label
    })
    }

However my styles are not showing up. Styles for other elements do show up.
