    <!-- put the component in a containing div -->
    <div class="image-swiper">
      <ngx-image-swiper [config]="swiperConfig" [images]="images"></ngx-image-swiper>
    </div>
  `,
  styles: [
    `
      // position must be relative
      // width & height can be whatever you want
      .image-swiper {
        position: relative;
        width: 600px;
        height: 600px;
