подскажите либу чтобы можно было сделать кастомный скролл для ie11, вид скроллбара снизу
Я не уверен, что это будет работать в IE11 (у меня нету никакого IE чтобы проверить). Если что-то не работает, напишите комментарий, исправим.
Писал второпях на коленях. Не судите строго.
Цвета скролла подкорректируйте в CSS.
Оригинальный скролл оставил, чтобы можно было отдебажить кастомный. Но код, который скрывает оригинальный скролл присутствует (закомментирован).
