在 RMarkdown 演示文稿中滚动幻灯片（revealjs）

Question

我正在尝试为所有幻灯片激活我的 revealjs 演示文稿中的垂直滚动选项。

我已经尝试在我的 .Rmd 中直接在 css 中添加溢出选项，这使得滚动条出现在演示文稿上，但我的幻灯片仍然溢出，我无法向下滚动。

我在这里做错了什么？谢谢

Answer 1

我能够使用以下方法做到这一点：

.slide {
    height: 750px;
    overflow-y: auto !important;
}

您可以将其添加到 css 样式的演示文稿中，

<style>
.slide {
    height: 750px;
    overflow-y: auto !important;
}
</style>

... 或在原始问题中的代码块中。

请注意，这仅在我还指定了高度以及 overflow-y 选项时才对我有用。
