The default font for revealjs presentations is too big. The [documentation ](https://quarto.org/docs/reference/formats/presentations/revealjs.html) says you can add 'smaller' to the yaml header to decrease the font size on all the slides, but it doesn't say what's suppose to come after it. Setting fontsize in the yaml header doesn't do anything either. 

For example

logo: logo.png
or
footer: 'Company tag line here'

but what about smaller? 

smaller: ????
