在用RMarkdown的ioslides编写演示文稿时,我遇到了一个问题,我一直无法找到解决方案。This answer也没有解决这个特定的问题。
有时,两列布局是最好的解释,一边是图像,另一边是文字。但是,如下面的示例所示,列中断似乎无法按需要工作。
有什么方法可以在特定的点上用强制列来打断?我曾经考虑过增加右边的图像高度,但不幸的是,有时这不是一个选择。

output:

## Slide Title {.columns-2 .smaller}
### Slide Subtitle
>- Some bullet points which take up some space space space space space space space
>- on the column on the left
>- which are then wrapped to the right column.
>- *Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.*
>- line break after this longer bullet point but intead it breaks in some strange place even though it would have space at the bottom of the left column!
<!-- the columns should break here -->

我过去用过两种方法,两种答案都是在你的问题上联系起来的。我是不是漏掉了为什么这些不符合你的需要?
方法1似乎是您所追求的,但我个人倾向于使用方法2,因为我喜欢具有不同宽度列的灵活性。
注意:我只使用ioslides格式测试了这些方法
方法1: forceBreak,内联样式标记
这需要定义一个额外的CSS类,您可以在文档的开头进行内联。

title: "Untitled"
output:
ioslides_presentation:
widescreen: true

<style>
.forceBreak { -webkit-column-break-after: always; break-after: column; }
</style>
## Slide Title {.columns-2 .smaller}
### Slide Subtitle
>- Some bullet points which take up some space space space space space space space
>- on the column on the left
>- which are then wrapped to the right column.
>- *Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.*
>- line break after this longer bullet point but intead it breaks in some strange place even though it would have space at the bottom of the left column!
<p class="forceBreak"></p>

方法2: HTML标记
此方法不需要任何额外的CSS定义或外部文件。

## Another Method for Two Column Layouts
<div style="float: left; width: 40%;">
+ This text is on the left
</div>
<div style="float: right; width: 60%;">
+ This text is on the right

通过在第二列下面添加一个空div,添加clear样式,从而阻止内容耗尽第二列下面的空间,从而禁用了下面元素的再流。
<div style="clear: both;"></div>我从这里发现了这个:https://css-tricks.com/all-about-floats/
