</div>

  float: left;

}

.handle-counter .counter-minus,  .handle-counter .counter-plus { text-align: center; }

.handle-counter input {
  width: 50px;

  border-left: none;
  border-right: none;
}

.btn {
  padding: 6px 12px;
  border: 1px solid transparent;
  color: #fff;
}

.btn:disabled, .btn:disabled:hover {
  background-color: darkgrey;
  cursor: not-allowed;
}

.btn-primary { background-color: #009dda; }
