我正在使用RMarkdown创建具有光泽的ioslide演示文稿. 我的某些幻灯片实际上无法放在一页上,并且被截断了.
I am using RMarkdown to create an ioslide presentation with shiny. Some of my slides do not actually fit on one page and are truncated.
由于这是HTML输出,因此我想添加一个滚动条以使长幻灯片可滚动.
Since this is a HTML output, I would like to add a scroll bar to make my long slides scrollable.
我已经进行了大量的搜索,发现了一个使R代码块可滚动的部分解决方案.但是,无论内容如何,我都希望使幻灯片可滚动.
I have been googling a lot and found a partial solution to make R code chunks scrollable. However I want to make my slides scrollable regardless of the content.
这是一个Rmd玩具示例,其中幻灯片不适合一页:
This is a toy Rmd example giving slides not fitting on one page:
--- title: "Untitled" date: "30 October 2018" output: ioslides_presentation runtime: shiny --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = FALSE) ``` ## Shiny Presentation - A very long - and boring - list of - bullet points - just a - toy example - obviously - not over yet - almost - not quite - finally - out of frame!我想使此幻灯片可滚动,因为它不适合一页.
I would like to make this slide scrollable since it does not fit on one page.
我不确定为什么要对此大加推销-不胜感激有建设性的意见:)同时,我确实删除了css标记,这可能使人们不熟悉rmarkdown.
I am not sure why this is being heavily downvoted - would appreciate a constructive comment :) In the meantime, I did remove the css tag which may have brought people not familiar with rmarkdown.
推荐答案自我解答:
使幻灯片可滚动(水平和垂直,但是如果只需要垂直滚动,则只需删除一行)的CSS就是:
The bit of CSS that will make the slide scrollable (both horizontally and vertically but you just have to remove one line if only vertical scrolling is needed) is:
slides > slide { overflow-x: auto !important; overflow-y: auto !important; }请注意,幻灯片是从ioslide获取高度的,因此无需指定高度(实际上,如果这样做,似乎会引入视觉毛刺).使用auto而不是scroll确保滚动条仅在有需要时出现.
Note that the slide gets a height from ioslide so there is no need to specify a height (and in fact it seems to introduce visual glitches if you do). Using auto instead of scroll makes sure a scrollbar only appears when there is a need.
您可以在<style>标签之间的Rmd中直接添加此CSS,也可以将CSS放在单独的文件中(例如scrollable_slides.css).
You can either add this CSS directly in the Rmd in between <style> tags or put the CSS in a separate file (e.g. scrollable_slides.css).
然后可以像这样将CSS文件添加到Rmd中(假设scrollable_slides.css与Rmd位于同一目录中):
The CSS file can then be added to the Rmd like this (assuming scrollable_slides.css is in the same directory as the Rmd):
--- title: "..." output: ioslides_presentation: css: 'scrollable_slides.css' runtime: shiny ---更多推荐
