<style type="text/css">

body, td {
   font-size: 14px;
}
code.r{
  font-size: 12px;
}
pre {
  font-size: 12px
}
</style>



- body, td, is for normal text
- code.r is for r code
- pre is for output of knitr chunks




This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r}
summary(cars)
```

You can also embed plots, for example:

```{r, echo=FALSE}
plot(cars)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

This works correctly, Thank you for the code!

Thank you

This does not work for ioslides. Could you recommend alternatives for ioslides?

Nice 👍

How about the font style? Can change it? Many thanks.

Hi @reddylee

Yes, just add the font name in font-family. For example:

<style type="text/css">

body, td {
  font-family: Calibri;
  font-size: 12px;
}
code.r{
  font-size: 9px;
}
pre {
  font-size: 10px
}
</style>
