与其他（未引用的）文本相比，Markdown上的引用文字字体通常太大。这是一个例子：

使用RStudio生成

Answer 1

这似乎是RMarkdown的html输出的默认CSS的一部分，其中blockquotes具有：

blockquote {
    padding: 10px 20px;
    margin: 0 0 20px;
    font-size: 17.5px;
    border-left: 5px solid #eee;
}

您可以通过创建自定义CSS文件来覆盖此文件，例如custom.css：

blockquote {
    padding: 10px 20px;
    margin: 0 0 20px;
    font-size: 14px;
    border-left: 5px solid #eee;
}

然后将其添加到RMarkdown doc的标题中：

---
title: "Untitled"
author: "Me"
output: 
  html_document:
    css: custom.css
---

Answer 2

作为外部 css 文件的替代方案，您可以使用 css 代码块：

---
title: "Example"
date: "`r Sys.time()`"
output: html_document
---

```{css style settings, echo = FALSE}
blockquote {
    padding: 10px 20px;
    margin: 0 0 20px;
    font-size: 14px;
    border-left: 5px solid #eee;
}
```

Now quotes will be as you wish
