セクションの中央揃え

Question

titlesec 次のようにセクションを中央揃えにしたいと思います(MWE):

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
\usepackage{titlesec}
\titleformat{\section}% command to format the section titles
        [block]% shape/type of title
        {\LARGE\bfseries}% formatting commands applied to both label and title
        {\begin{center} \thesection \end{center}}% section number; here set inside an invisible box with a constant width
        {0em}% separation between number and chapter title; we've already covered this with the box
        {}% additional formatting command for title itself not applied to number
        [
        ]%
\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}

しかし、これではセクションのタイトルが中央に配置されず、見た目もあまり美しくありません。 を使用してセクションを美しく中央に配置するにはどうすればよいでしょうかtitlesec?

Answer 1

cfr の提案\centeringに従って実行すれば動作します。\LARGE\bfseries

\titleformat{\section}% command to format the section titles
        [block]% shape/type of title
        {\LARGE\bfseries\centering}% formatting commands applied to both label and title
        {\thesection}% section number; here set inside an invisible box with a constant width
        {1ex}% separation between number and chapter title; we've already covered this with the box
        {}% additional formatting command for title itself not applied to number
        [
        ]%

与える

簡易形式を使用することもできます

\titleformat*{\section}{\LARGE\bfseries\centering}

の代わりに\titleformat。

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
\usepackage{titlesec}
%\titleformat{\section}% command to format the section titles
%        [block]% shape/type of title
%        {\LARGE\bfseries\centering}% formatting commands applied to both label and title
%        {\thesection}% section number; here set inside an invisible box with a constant width
%        {1ex}% separation between number and chapter title; we've already covered this with the box
%        {}% additional formatting command for title itself not applied to number
%        [
%        ]%

\titleformat*{\section}{\LARGE\bfseries\centering}
\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}

Bernard が指摘したように、の代わりに\filcenterprovided byを使用することもできます。titlesec\centering

sectstyしかし、可能であれば、AboAmmar の回答のように簡単に使用できるでしょう。

Answer 2

sectstyパッケージを使用した簡単な解決策

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
%\usepackage{titlesec}
\usepackage{sectsty}

\allsectionsfont{\centering}

\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}

または、次のようにオプションtitlesecを追加して単純に使用します[center]。

\documentclass[10pt,a4paper,twoside]{book}
\usepackage[latin1]{inputenc}
\usepackage{lipsum}
\usepackage[center]{titlesec}

\begin{document}
\chapter{The first chapter}
\lipsum[1-5]
\section{First section}
\lipsum[3]
\section*{Section}
\lipsum[4]

\end{document}
