1. 前言
创作开始时间：2021年12月12日21:21:07
感觉用LaTeX很简单，因为Overleaf上的模板太多了，但是要精通LaTeX，感觉要掌握的东西太多。本文主要对LaTeX Beamer中的字体设置进行研究。
备注：
第4节：“直接上代码！”包含实例代码。可以直接跳到这一节查看。
2. 关于字体
LaTeX的字体属性有四种：
familyshapeseriessize其中family属性主要可以归为三类：
serif 有衬线字体sans serif （也叫做roman）。无衬线字体monospaced 等宽字体对于中文来说，宋体属于serif 字体，而黑体、幼圆、雅黑则属于sans serif 字体。
而英文，常用的 serif 字体为Times New Roman，常用的 sans serif 字体为Arial，Tahoma。

首先，所有的字体：
Fontname https://mirror-hk.koddos.net/CTAN/info/fontname/fontname.pdf 这个是官方文档overleaf支持的字体没有那么多，具体可见官网（也挺多了）：
Which OTF or TTF fonts are supported via fontspec? https://es.overleaf.com/learn/latex/Questions/Which_OTF_or_TTF_fonts_are_supported_via_fontspec%3F4. 直接上代码！
documentclass[xcolor=dvipsnames,9pt]{beamer} % 使用theme usetheme{CambridgeUS} useinnertheme{circles} % 使用字体必备的包 usepackage{fontspec} # 定义字体 newfontfamilychalkd{DejaVu Sans} # 设置beamer的字体 setbeamerfont{normal text}{family=chalkd,series=mdseries} setbeamerfont{alerted text}{family=chalkd,series=bfseries} setbeamerfont{frametitle}{family=chalkd,series=bfseries} % ,size={fontsize{32}{36}} AtBeginDocument{usebeamerfont{normal text}} title[Example]{Just an example!} author[xxx]{xxx} date{9th Dec, 2021} begin{document} begin{frame} titlepage end{frame} section{Hello world} begin{frame}{Hello world now.} Hello world to every one. end{frame} end{document}
1234567891011121314151617181920212223242526272829303132333435效果如下：
DejaVu Sans是一种无衬线字体。
换成：Alfios（一种有衬线字体，从https://es.overleaf.com/learn/latex/Questions/Which_OTF_or_TTF_fonts_are_supported_via_fontspec%3F oveleaf官网找的）之后，就变成了下面的样子：
4.1. 做过的错误尝试
使用setmainfont{font/Palatino.ttf}或者setmainfont{palatino}，貌似setmainfont对Beamer没用。使用setmainfont[ExternalLocation=font/]{POLYA.OTF}[Ligatures=TeX]，没用defaultfontfeatures{Ligatures=TeX}，没用使用overleaf官方提供的example:setromanfont{Times New Roman} setsansfont{Arial} setmonofont[Color={0019D4}]{Courier New} 123
也没用。
还看了很多别的操作，试了下都没用。。。找到有用的还是费了不少时间的。5. 小结
