HTML-страница с CSS и начальной загрузкой не отображает карты последовательно

Question

У меня есть базовая страница начальной загрузки и html-страница с css, и хотя первая «карта» отображается правильно, все остальные имеют разные размеры. Как ни странно, и, возможно, это ключ к решению проблемы, когда размер страницы уменьшается (например, до размера мобильного устройства), тогда все карточки имеют одинаковый размер.

Может ли кто-нибудь предложить исправление, гарантирующее, что все карты имеют одинаковый размер при полном размере страницы?
