Я работаю над совой-каруселью. Я хочу, чтобы все элементы с одинаковой высотой, когда было добавлено больше содержимого, не совпадали по высоте.Я попытался с flex-свойствами, но не понимаю, почему он не работает.Пожалуйста, кто-нибудь, укажите мне правильное направление, я действительно застрял в этом.Заранее спасибо Вот это codepen
