Caption font color with kable

Question

Using kable() to render a simple table yields what seems to be the default pale font color for the table caption in the resulting html file. Is there a way to control the table (or figure) caption font color, size, etc?

    output: 
    html_document: 
    theme: cosmo

    ```{r}
    library(knitr)
    tab.1 = table(mtcars$cyl, mtcars$vs)
    kable(tab.1, caption="Table 1: Caption Font Color")
    ```

Answer 1

Aha! Customizing the CSS stylesheet does the trick.

    caption {
      color: red;
      font-weight: bold;
      font-size: 1.0em;
    }
