Tips 💡

You don't need to remember all CSS classes. Just use the Bootstrap Editor instead.

Sass source

/* _card.scss:279 */
.accordion {
  .card:not(:first-of-type):not(:last-of-type) {
    border-bottom: 0;
    border-radius: 0;
  }

  .card:not(:first-of-type) {
    .card-header:first-child {
      border-radius: 0;
    }
  }

  .card:first-of-type {
    border-bottom: 0;
    border-bottom-right-radius: 0;
    border-bottom-left-radius: 0;
  }

  .card:last-of-type {
    border-top-left-radius: 0;
    border-top-right-radius: 0;
  }
}
