如何修改R语言Flexdashboard中项目符号文本的字体与字号？

你之前使用的.chart-title CSS选择器仅针对图表标题，无法作用于无序列表（项目符号）文本。要修改这类内容，需要针对无序列表的元素设置样式：

正确的CSS配置 #

在你的flexdashboard文档开头（YAML配置之后）添加一次全局样式即可，无需重复添加：

<style type="text/css">
/* 修改无序列表（项目符号）文本的字体与字号 */
.storyboard-body ul li {
  font-size: 18px; /* 自定义字号，可按需调整 */
  font-family: "Arial", sans-serif; /* 自定义字体，可替换为其他可用字体 */
}

/* 如需保留图表标题的样式修改可保留此部分 */
.chart-title {
  font-size: 30px;
  font-family: Algerian;
}
</style>

title: "HTML Widgets Showcase"
output: 
  flexdashboard::flex_dashboard:
    storyboard: true
    social: menu
    source: embed
---

<style type="text/css">
.storyboard-body ul li {
  font-size: 18px;
  font-family: "Arial", sans-serif;
}

.chart-title {
  font-size: 30px;
  font-family: Algerian;
}
</style>

Leaflet is a JavaScript library for creating dynamic maps that support panning and zooming along with various annotations. #

library(leaflet)
leaflet() %>%
  addTiles() %>%
  addMarkers(lng=174.768, lat=-36.852, popup="The birthplace of R")

https://rstudio.github.io/leaflet/

• Interactive panning/zooming

• Compose maps using arbitrary combinations of map tiles, markers, polygons, lines, popups, and GeoJSON.

• Create maps right from the R console or RStudio

• Embed maps in knitr/R Markdown documents and Shiny apps

• Easily render Spatial objects from the sp package, or data frames with latitude/longitude columns

• Use map bounds and mouse events to drive Shiny logic

d3heatmap creates interactive D3 heatmaps including support for row/column highlighting and zooming. #

library(d3heatmap)
d3heatmap(mtcars, scale="column", colors="Blues")

https://github.com/rstudio/d3heatmap/

• Highlight rows/columns by clicking axis labels

• Click and drag over colormap to zoom in (click on colormap to zoom out)

• Optional clustering and dendrograms, courtesy of base::heatmap

## 补充说明
- `.storyboard-body ul li` 是针对storyboard布局下无序列表项的精准选择器，确保样式仅作用于你需要的项目符号文本；
- 若要全局修改文档中所有无序列表，可简化选择器为 `ul li`；
- 选择字体时需确保渲染环境支持该字体，避免使用系统未安装的特殊字体。
