Some basic documentation can be found here.

How to get different custom CSS (font color) of kable headers with consecutive tables?

I want a blue caption then a red caption. I cat two HTML <style>...</style> sections, first blue second red, according to this answer, but I get both red.

How to get a blue then a red caption?

    Because second css overwrites the first css.

    Better to do like this:

    cat("
<style>
.blue-caption {
      color: blue;
    }

.red-caption {
      color: red;
    }
</style>
")

    and then use like this:

    caption='<span class="blue-caption">Caption blue</span>',
caption='<span class="red-caption">Caption red</span>',

    Works?

    Rather than specifying the CSS in each chunk, you can also give a special HTML class to each table and then gather all styling in a css chunk:

    ---
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo=FALSE)
```

```{css}
.mytable1 > caption {
    color: blue;
}
.mytable2 > caption {
    color: red;
}
```

```{r results="asis"}
knitr::kable(head(iris), 
             format="html",
             digits=4,
             row.names=FALSE,
             caption='Caption blue',
             escape=TRUE)|>
  kableExtra::kable_styling(font_size=14, htmltable_class = "mytable1") |>
  kableExtra::kable_paper(c('hover', 'condensed', 'responsive'), full_width=T) |>
  kableExtra::scroll_box(width="100%", height="200px") 
```


```{r results="asis"}
knitr::kable(head(iris), 
             format="html",
             digits=4,
             row.names=FALSE,
             caption='Caption red',
             escape=TRUE) |>
  kableExtra::kable_styling(font_size=14, htmltable_class = "mytable2") |>
  kableExtra::kable_paper(c('hover', 'condensed', 'responsive'), full_width=T) |>
  kableExtra::scroll_box(width="100%", height="200px")
```

    Alternatively we could insert inline css outside of a chunk.

    <style>
.mytable1 > caption {
  color: blue;
}
.mytable2 > caption {
  color: red;
}
</style>
