你好，

我希望灰色框始终以内侧页面的镜像如果连续页面上有两个章节（参见第 2 页和第 3 页）。有什么想法吗？

谢谢 Nico

Answer 1

使用\ifthispageodd{}{}Komma-Script 包的宏，您可以测试页面何时为奇数，从而更改章节的定义。

您没有说明如何处理章节名称。在这种情况下，保留在左侧。如果您想镜像位置，宏\node也应该更改。

          {
          \draw[fill=gray!15, draw=gray] (0.1\paperwidth,0) rectangle(1\paperwidth,3cm);       
          \node[anchor=east,yshift=1.5cm,xshift=0.9\paperwidth, text width=1.05\textwidth]{\textbf{\huge{#1}}};
          }
        \end{tikzpicture}
      };
   \end{tikzpicture}
   }

%adjust spacing for correct alignment of following text
\titlespacing*{\chapter}{0pt}{50pt}{0pt}

\begin{document}

\chapter{One}
\blindtext[4]
\chapter{Two}
\blindtext[4]
\chapter{Three}
\blindtext[4]

\end{document}
