在部分中使用 raisebox 时换行

raisebox在使用命令时如何换行\section。我的 MWE 是：

\documentclass{book}
\usepackage[explicit]{titlesec}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{xcolor,lipsum,mdframed}

\definecolor{sectcolor}{cmyk}{0,1,.75,.39}
\definecolor{sectbgcolor}{RGB}{0,106,168}
\definecolor{sectsubbgcolor}{RGB}{0,139,191}

\renewcommand{\thesection}{\thechapter\Alph{section}}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{\thesection.\ #1}}

\makeatletter
\titleformat{\section}
  {\fontsize{18}{20}\selectfont\color{white}\bfseries}
  {\llap{\smash{\parbox[t]{2em}{\raggedleft%
      \colorbox{sectcolor}{%
        \makebox[\dimexpr2em-2\fboxsep\relax][r]{%
          \hfill\strut\thesection
        }%
      }\\[1ex]
    \includegraphics[width=1.5em]{image-1}\\[2pt]
    \includegraphics[width=1.5em]{image-1}\\[2pt]
    \includegraphics[width=1.5em]{image-1}\\[2pt]
    }}\hspace*{0.5em}}%
  }
  {0em}
  {\makebox[\linewidth][l]{\colorbox{sectbgcolor}{\parbox[t]    {\dimexpr\paperwidth-\oddsidemargin-1in-2\fboxsep-5pt\relax}{%
    \strut\fontsize{18}{20}\selectfont\raisebox{-2.5pt}[0pt][0pt]{#1}%
    \if\sectionsubtitle\empty
    \else
      \hspace{5pt}\smash{\colorbox{sectsubbgcolor}    {\strut\large\sectionsubtitle}}%
    \fi}
    }}%
  }

\makeatother

\def\sectionsubtitle{\empty}
\newcommand\Ssection[3][]{%
  \gdef\sectionsubtitle{#3}\section[#1]{#2}\gdef\sectionsubtitle{\empty}%
}

\begin{document}

\chapter{Chapter Title Here}
\section{Count systems}
\lipsum[1]
\Ssection{Number systems}{Consolidating}
\lipsum[1]
\Ssection{Highest common factor and lowest common\hfil\break     multiple}{Consolidating}
\end{document}

答案1

首先，您不应该手动给标题添加换行符。您应该设置标题宏，以便根据需要将其分散到多行。对于您来说，构建一个框来容纳背景颜色，并在parbox里面放置一个框来容纳文本即可实现这一点。

其次，我认为您使用的是 raisebox，因为高度和深度不正确。这似乎是由于使用了错误的 造成的\strut。您的编码\strut\fontszie{...}\selectfont意味着 strut 未调整到新的字体大小。相反，请按以下顺序编写 `\fontsize{...}\selectfont\strut。
