## 6.8 Sans-serif fonts and epigraphs

There are a few other things in Tufte CSS that we have not mentioned so far. If you prefer sans-serif fonts, use the function sans_serif() in tufte. For epigraphs, you may use a pair of underscores to make the paragraph italic in a block quote, e.g.,

> _I can win an argument on any topic, against any opponent.
>  People know this, and steer clear of me at parties. Often,
>  as a sign of their great respect, they don't even invite me._

> r quote_footer('--- Dave Barry')
