我正在研究几个属于一起的乳胶模板（信件、文章、报告）。我已经实现了几乎所有目标，除了一个目标，使用\documentclass[.pt]{}命令更改字体大小，无论我使用 9pt 还是 12pt，我的文档看起来都一样。如何确保这适用于我的自定义类？

只是一些旁注，我使用 XeLaTex 编译我的文档，同时使用 fontspec 包和\setromanfont{DejaVu Serif}命令安装字体（DejaVu 家族）。这些类可以选择在系列中的衬线字体和无衬线字体之间切换。

这是我的最小工作示例： 由letter.tex文件组成。

% !TeX encoding = UTF-8
% !TEX TS-program = xelatex

\documentclass[12pt, british]{letter-Bram}

% Sender information
\signature{Sender Full Name}
\address{Sender\\ Adress line 1\\ Adress line 2\\ Country}

\begin{document}
\begin{letter}{Recipient\\ Organization\\ Adress line 1\\ Adress line 2\\ Country}
    \opening{Dear Recipient,}
    This letter is send from the sender to the recipient, and styled in a sans-serif font. The class has the following class settings:
    \begin{description}
        \item[sans] To turn the document and math into a sans serif font.
        \item[lanuage] You can specify the language like normal. For example \enquote*{dutch}, \enquote*{british}, \enquote*{german}, defaults to \enquote*{american}. I recommend specifying a language as this does set quotation marks, date notations, hyphenation and others.
    \end{description}

    Here is an example equation:
    \begin{equation}
        a x^2 + b x + c = 0
    \end{equation}
    which can be solved with the standard $abc$ formula.

            
    \closing{Kind Regards,}
\end{letter}
\end{document}

这是letter-Bram.cls类文件。

我很确定我错过了一些非常明显的东西，但找不到。

两个问题：

  • 您的班级正在加载letter班级，但将其选项传递给article班级。下定决心，你真正想要的两个课程中的哪一个

  • 9pt不是一个有效的选项，请尝试使用10ptvs。12pt
