I would like to have different font size in different sections of r markdown, here is an example:
```{r psection 1}
# I would like to have font size 20
print("Hello, World!")
```
```{r psection 2}
# I would like to have font size 10
print("Hello, World!")
```
I wonder if this is possible? So far my understanding that font size must state the same for whole document (except headers).
