Покажу пример, как сделать простой и легкий слайдер на ванильном JavaScript без использования библиотек.
Чтобы сделать красивый легкий слайдер с возможностью перетаскивания слайдов, совершенно не обязательно подключать jQuery и использовать разные популярные библиотеки типа SwiperJs и Owl Carousel. Потребуется только HTML, CSS и JS.

Более продвинутые могут взять код и внедрить его в свой проект.
