嗨！！我已经制作了这个标题，但我无法设置背景颜色。我是 Latex 新手，我觉得这很难。有人能帮我吗？
我的工作是：
\documentclass[14pt,a4paper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage{titlesec, color}
\usepackage{theorem}
\newtheorem{worked example}{Worked Example}[chapter]
\newtheorem{solution}{SOLUSION}[chapter]
\usepackage{anyfontsize}
\usepackage{amsfonts}
\usepackage{textcomp}
\usepackage{enumerate}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhead{}
\renewcommand{\chaptermark}[1]{\markboth{\textbf{\thechapter \ | \ #1}}{}}
\fancyhead[LE]{\hspace{30pt}\textbf{\thepage} \hspace{20pt} \leftmark}
\renewcommand{\sectionmark}[1]{\markright{\textbf{\thesection \ | \ #1}}}
\fancyhead[RO]{\rightmark \hspace{20pt} \textbf{\thepage} \hspace{30pt}}
\fancyfoot{}
\addtolength{\headwidth}{\marginparsep}
\addtolength{\headwidth}{\marginparwidth}
\renewcommand{\headrulewidth}{}
\renewcommand{\footrulewidth}{}
\setlength\headheight{50pt}
\newcommand{\hsp}{\hspace{20pt}}
\newcommand{\ntl}{\newline \newline}
\titleformat{\chapter}[hang]{\fontsize{50}{60}\bfseries\color[rgb]{0,0.5,0.75}}{\thechapter\hsp\fontsize{90}{60}\selectfont\textcolor{black}{|}\hsp}{0pt}{\Huge\bfseries}
\titleformat{\section}{\large\bfseries}{}{0pt}{\textcolor[rgb]{0,0.5,0.75}{Topic \thesection} \ }[{\titlerule[0.8pt]}]
\begin{document}
\chapter{\textcolor{black}{NUMBER}}
\section{BIDMAS.}
\thispagestyle{empty}
.

\end{document}

解决方案是使用titleps代替：只需使用选项fancyhdr加载。您不必与标记作斗争：只需使用和定义新的页面样式即可。 可以很好地合并到 中，这样可以节省在每个新章节中键入它的时间。titlesecpagestyles\sectiontitle\chaptertitle\thispagestyle{empty}\titleformat[\chapter}
\documentclass[14pt,a4paper,twoside]{extbook}
\usepackage[utf8]{inputenc} %
\usepackage[T1]{fontenc}

%\usepackage{anyfontsize}
\usepackage{amsfonts}

\usepackage{enumerate}
\setlength\headheight{21pt}
\newcommand{\hsp}{\hspace{20pt}}
\newcommand{\ntl}{\newline \newline}
\titleformat{\chapter}[hang]{\fontsize{50}{60}\bfseries\color[rgb]{0,0.5,0.75}}{\thechapter\hsp\fontsize{90}{60}\selectfont\textcolor{black}{|}\hsp}{0pt}{\thispagestyle{empty}\Huge\bfseries}
\titleformat{\section}{\large\bfseries}{}{0pt}{\textcolor[rgb]{0,0.5,0.75}{Topic \thesection} \ }[{\titlerule[0.8pt]}]
\usepackage{blindtext}
\newpagestyle{mine}{%
\setlength\fboxsep{10pt}
\sethead[\bfseries\llap{\colorbox{SteelBlue3}{\parbox{\dimexpr\marginparsep + \marginparwidth\relax}{\hspace{20pt}\color{white}\thepage\vphantom{|}}}}%
\colorbox{SlateGray2!40}{\parbox{\dimexpr\linewidth-2\fboxsep}{~\thechapter~|\hspace{0.75em}\chaptertitle}}][][]%

\setfoot{}{}{}
}
\pagestyle{mine}
\begin{document}
\chapter{{NUMBER}}%\textcolor{black}
\section{BIDMAS.}
\blindtext[10]
\end{document}
答案2
\headrulewidth和\footrulewidth是必须包含长度的宏。0pt用于让规则消失：
\renewcommand*{\headrulewidth}{0pt}
\renewcommand*{\footrulewidth}{0pt}
然后，示例显示\colorbox，示例代码（用编译pdflatex）：
\documentclass[a4paper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage{color}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhead{}
\renewcommand{\chaptermark}[1]{%
\markboth{\textbf{\thechapter \ | \ #1}}{}%
}
\fancyhead[LE]{%
\hspace{30pt}\textbf{\thepage} \hspace{20pt} %
\colorbox[rgb]{0,0.5,0.75}{\leftmark}%
}
\renewcommand{\sectionmark}[1]{%
\markright{\textbf{\thesection \ | \ #1}}%
}
\fancyhead[RO]{%
\rightmark \hspace{20pt} \textbf{\thepage} \hspace{30pt}%
}
\fancyfoot{}
\addtolength{\headwidth}{\marginparsep}
\addtolength{\headwidth}{\marginparwidth}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}
\setlength\headheight{50pt}
\begin{document}
\chapter{\textcolor{black}{NUMBER}}
\section{BIDMAS.}
\thispagestyle{empty}
\newpage
Foo.
\newpage
Bar.
\end{document}
