Адаптация слайдера?

Question

[vvk996]

Проблема в том что слайдер в начале не был адаптивным и ширина блоков задается скриптом, удалось добиться адаптивности ширина берется от ширины окна. Тоесть при загрузке страницы ставятся размеры и оно работает но если изменить окно без перезагрузки страницы размеры не меняются. Помогите адаптировать
Вот сайт со слайдером (не реклама)(Он на начале адаптации и сейчас интересует именно слайдер) ДЕМО
Код прилагаю
