  border-right: 1px solid black;

Answer 1

Use h-100 to nested row

See sizing in bootstrap-4:https://www.w3schools.com/bootstrap4/bootstrap_utilities.asp

.price {
  border-left: 1px solid black;
  border-right: 1px solid black;
}
.price:first-child{
  border-left:none;
}
.price:last-child{
  border-right:none;
}
