我正在尝试创建一个命令，使我能够在文档的边缘添加一些“重要注释”。只要我使用框的“左”选项并且页码是奇数，我就能让它工作。但是当我尝试将其放在偶数页上时，无论我使用“左”还是“右”选项，它都不会显示任何内容。
\documentclass[a4paper,11pt]{book}
\usepackage[outer=5cm, heightrounded, marginparwidth=4cm, marginparsep=0.5cm]{geometry}
\usepackage[T1]{fontenc} % to get Type 1 fonts
\usepackage[utf8]{inputenc} % to enable non ASCII characters
\usepackage{lmodern}
\usepackage[english]{babel}
\usepackage{marginnote}
\usepackage{xcolor}
\usepackage[most,breakable,many]{tcolorbox}
\tcbset{before skip=0pt,after skip=0pt}
\usepackage{lipsum} % dummy text
%%%%%%%%%%%%%%%%%%%%%%%%% Important Note %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newcounter{important}
\newtcolorbox[use counter=important]
{important}[1][]
{title=Important Note~\thetcbcounter,
width=4cm,
left=0pt,
right=0pt,
fonttitle=\bfseries\color{white},
colframe=olive,
colback=olive!10,
#1
}
\newcommand\Limportant[3][]{%
\marginnote[#1]{%
\makebox[0pt][l]{\begin{important}[label=#3]
#2
\end{important}}}}%
\newcommand\Rimportant[3][]{%
\marginnote[#1]{%
\makebox[0pt][r]{\begin{important}[label=#3]
#2
\end{important}}}}%
\begin{document}
\lipsum[1]
\Limportant[-2cm]{\lipsum[75]}.
\vfill
\pagebreak
\lipsum[1]
\Rimportant{\lipsum[75]}.
\end{document}
理想情况下，我想结合这两个选项，以便它自动决定应该放在哪一侧，但我还没有弄清楚如何计算 '$'\pagenumber modulo 2 '$'，所以我可以将其作为带有案例的命令包含在内。
在同一个命令中我可能写错了什么，因为添加用于垂直调整的可选命令没有效果（'$'\Limportant[-2cm]{\lipsum[75]}'$' 处的 -2cm）
答案1
无需使用if odd page等选项tcolorbox
参数等存在一些问题，例如错误使用\marginnote。
