Адаптивная кнопка меню не отображается в адаптивном представлении

Question

Навбар сработал и внезапно остановился. Ранее оно также исчезло. Но мне удалось решить эту последнюю проблему с помощью z-index. Для мобильного я разместил кнопку меню в правом нижнем углу. При нажатии это позволяет расширить меню. В настоящее время кнопка исчезла и не может появиться снова. В адаптивном представлении расположение меню изменилось. Это было не так раньше. Интересно, в чем причина? Я просмотрел код много раз. Ничего не работает

Answer 1

Можете ли вы установить .responsive-bar{display:block}. Надеюсь, это вам поможет.

@media screen and (max-width: 900px) {
  .responsive-bar{display:block}
}

Answer 2

Когда вы используете media screen, вам нужно добавить ключевое слово and между screen и (width)

. У вас 3 пропущенных скобки для медиазапросов. Пожалуйста, используйте CSS валидаторы онлайн или IDE.

Answer 3

Похоже, ваши медиа-запросы не приходят. Я думаю, это потому, что вы пропускаете и в своих медиа-запросах.

Попробуйте:

@media screen and (max-width: 900px) {
  /* Your CSS */
}

Вместо:

@media screen (max-width: 900px) {
  /* Your CSS */
}

Редактировать: также я вижу некоторые медиа запросы в вашем CSS коде не закрыты. Тебе лучше проверить это. См. Медиазапрос '@media screen (max-width: 900px) {' в вашем коде, например.
