<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.

It works well. Thank you.

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>
