我正在尝试使用此示例环境在我的书中。我真的很喜欢它在示例旁边创建垂直线的方式。我想自定义外观，但这是一个单独问题。
在这个问题中，我想关注另一个问题。当我在我的 中使用它时kaobook，它会改变 kaobox 环境内的列表的缩进：
\documentclass[
fontsize=10pt, % Base font size
twoside=false, % Use different layouts for even and odd pages (in particular, if twoside=true, the margin column will be always on the outside)
%open=any, % If twoside=true, uncomment this to force new chapters to start on any page, not only on right (odd) pages
%chapterprefix=true, % Uncomment to use the word "Chapter" before chapter numbers everywhere they appear
%chapterentrydots=true, % Uncomment to output dots from the chapter name to the page number in the table of contents
numbers=noenddot, % Comment to output dots after chapter numbers; the most common values for this option are: enddot, noenddot and auto (see the KOMAScript documentation for an in-depth explanation)
%draft=true, % If uncommented, rulers will be added in the header and footer
%overfullrule=true, % If uncommented, overly long lines will be marked by a black box; useful for correcting spacing problems

注意第一个和第二个kaobox列表的缩进是正确的。但是在带有红色垂直线的示例之后，kaobox后面的所有内容的缩进都是错误的。
以下是一个链接Overleaf 项目，如果有帮助的话。

使用\usepackage{styles/mdftheorems}; 添加到您的 MWE
\newmdenv[
style=kaoboxstyle,
backgroundcolor=Cyan!15!White,
frametitlebackgroundcolor=Cyan!15!White,
]{objective}
并纠正
\NewDocumentEnvironment{bookexample}{O{}O{}}
{%
\colorlet{colexam}{red!55!black} % Global example color
\begin{bookexamplebox}[#1][#2]
}{\end{bookexamplebox}}% changed <<<
解决了问题。
