如何为列表文本应用点大小、sffamily 字体和颜色，已经有列表标签选项，是否有任何方法可以使用 enumitem 包应用列表文本？请查看我的 MWE 文件：
\documentclass{book}
\usepackage{enumitem}
\usepackage{color}
\setlist[enumerate,1]{font={\rmfamily\bfseries\color{red}},labelsep=4.2pt,
leftmargin=*,itemsep=0pt,topsep=0pt,align=right,
parsep=0pt,partopsep=0pt,rightmargin=0pt,itemindent=0pt,}%widest=10.
}

使用before此键是错误的 - 更改的字体大小将影响上一段的基线跳跃。正确的键是键first：

\usepackage{enumitem}
\usepackage{color}
\setlist[enumerate,1]{
before={\sffamily\itshape\color{blue}\footnotesize}
}
\begin{document}
