Я пытаюсь активировать опцию вертикальной прокрутки в моей презентации discoverjs для всех слайдов.
Я попытался добавить опцию переполнения в CSS непосредственно в моем .Rmd, что заставляет полосы прокрутки появляться в презентации, но мой слайд все еще переполняется, и я не могу прокручивать вниз.
Что я здесь делаю не так? Спасибо

## Slide with Bullets
This is a very very very long slide.

Я смог сделать это, используя:
.slide {
height: 750px;
overflow-y: auto !important;
}
Вы можете добавить это в свою презентацию в стилях css,
<style>
.slide {
height: 750px;
overflow-y: auto !important;
}
</style>
... или в фрагменте кода, как в исходном вопросе.
Обратите внимание, что это сработало для меня только тогда, когда я также указал высоту вместе с параметрами переполнения-y.
