r - 将 rmarkdown html 输出的标题设为粗体并分成 2 行

Question

我尝试使用以下代码来证明正文并使标题加粗。我想选择换行符在我的长标题中的位置，但是当我编织 rmd 文件时，标题部分不会发生任何样式编辑。

title: "my really really really really \n  really really long title"
author: "person"
date: "4/24/2020"
output:
  html_document:
    toc: true
    toc_float:
      collapsed: true
      smooth_scroll: false
    toc_depth: 4
    theme: yeti 
    highlight: tango

<style>
body {
text-align: justify}
title {
font-style: bold}
</style>

Answer 1

您可以在 YAML 中格式化标题. **text**用于使标题加粗和<br>打破这条线。
