And animation banners wraper have bad hight:

.#{$card-ns}c-card.#{$card-ns}c-card--big {
  height: 295px;

  @include breakpoint(medium down) {
    height: 290px;
  }
}

correct is:

.#{$card-ns}c-card.#{$card-ns}c-card--big {
  height: 295px;

  @include breakpoint(medium down) {
    height: 304px;
  }
}
