R markdown flexdashboard 文本边距

Question

如何在 rmarkdown flexdashboard 文档中为文本创建漂亮的边距？ Their manual site 是使用 flexdashboard 创建的，文本很好地跨越了中间的可读区域，并且没有到达屏幕的两侧。边距很好地适应浏览器窗口的宽度。尽管多次尝试指定{data-width} 和{data-padding}，但我无法重现此行为。我的文本总是从一边到另一边，这在宽浏览器窗口中看起来不太好。示例 Rmd 文件：

---
title: "Text width problem"
output:
  flexdashboard::flex_dashboard:
    orientation: rows
---

通过使用 CSS 设置文档样式。在这里，我们缩小了整个文档。

title: "Text width problem"
output:
  flexdashboard::flex_dashboard:
    orientation: rows

<style>
body {
  padding: 0px 200px 0px 200px;
}
</style>

另一种方法是使用特定 ID 将 div 容器包裹在您的文本周围

<div id="myText">
....
</div>

然后修改

<style>
#myText {
  width: 300px;
  margin: auto;
}
</style>
