Как мне улучшить навигацию, чтобы при изменении размеров она учитывала изменение размера экрана?

Question

Я все еще относительно новичок в создании веб-сайта и работаю над тем, чтобы узнать, что я делаю неправильно, но могу ли я получить помощь в понимании того, что неправильно в моем текущем сценарии и что я могу сделать, чтобы улучшить его?,При необходимости можно добавить мои css и java, но если есть что-то, что я могу сделать, чтобы исправить мой основной HTML-макет, пожалуйста, дайте мне знать.
