Я следую учебному пособию по адаптивному веб-дизайну и просто не могу разобраться с этой проблемой.Я включил файл grid.css в мой html, но кое-что из-за того, что chrome отображает его неправильно.Вместо сетки я получаю строки, как на прикрепленном изображении.Может кто-нибудь помочь мне с этим?Спасибо
Нет сетки
