Design for Serie, Movies and TV Details

.serie,
.movie,
.tv-details {
  &__content-wrapper {}

  &__content-wrapper,
  &__category {}

 
  &__title {
    @include setFont(('content-load', 'title', 'desktop'));
    margin-top: 10px;

    @include breakpoint($phone) {
      @include setFont(('content-load', 'title', 'mobile'));
    }
  }

  &__media {
    margin: 30px 0;
  }

  &__summary {
    @include setFont(('content-load', 'information', 'desktop'));

    @include breakpoint($phone) {
      @include setFont(('content-load', 'information', 'mobile'));
    }
}
