I'd like to use 3-4 different specific system fonts (e.g., Georgia, HelveticaNeui Light, and Lucida Sans) with certain font sizes for different sections of a page. How would I do this?
Edit: Thanks for the responses. I saw the fontspec package but the examples I found defined in the preamble \setmainfont{}, \setsansfont{}, etc. I couldn't figure out how to define a fontfamily and then reference it for a particular section. Here's an example:
\documentclass[12pt]{article}
\usepackage{fontspec}
\begin{document}
\section{Georgia}%here define font
This text shows in Georgia.
\section{Lucida Sans}%
This text shows in Lucida Sans
\section{HelveticaNeue Light}%here define font
This text shows in Helvetica Neue Light
\end{document}
