Боковая панель находится слева от экрана, оболочка имеет display: flex для достижения этой цели. Я хочу, чтобы .sidebar не прокручивался, когда содержимое превышало высоту #content. Другими словами, только .card должен быть прокручиваемым, но не #content.

Answer 1

Используйте следующие стили

.wrapper {
  display: flex;
}
.sidebar {
  height: 100vh;
  overflow-y: auto;
}
#content {
  flex-grow: 1;
}
#content .card {
  overflow-y: auto;
  height: calc(100vh - 40px); /* Total height - heinght of the navbar*/
}

Это похоже на реализацию боковой панели на сайте bootstrap.

.wrapper {
  display: flex;
}

.sidebar {
  width: 200px;
  height: 100vh;
  overflow-y: auto;
}

#content {
  flex-grow: 1;
}

#content .card {
  overflow-y: auto;
  height: calc(100vh - 40px);
  /* Total height - heinght of the navbar*/
}

Answer 2

установить overflow-y свойство равным auto. Вы также можете указать max-height для хранения карты div

style="max-height: 100px; overflow-y:auto"

Answer 3

Вы пытались установить следующее в вашей таблице стилей CSS?

.wrapper #content .card{
overflow-y: scroll;}

Это установит свойство прокрутки в направлении y только для выбранной карты. В качестве альтернативы вы можете использовать: <div class="card" style="overflow-y: scroll;">
