标题在正文之前

Question

我正在使用 LaTeX 写学习笔记。我想用一个标题来介绍我将要讨论的内容。我不希望：文本为粗体，标题为编号。有什么方法可以实现这一点吗？哦，还有，我希望标题和正文之间的间距合适。这是我目前正在做的一个例子，即我使用 center 环境以及 vspace。

我的代码：

\begin{center} This is what I'd like to have \end{center}

\vspace{2mm}
\begin{center} This is what I'd like to have \end{center}

Answer 1

像这样吗？

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{titlesec}%
\titleformat{\section}[block]{\filcenter\Large\scshape}{}{0ex}{}
\titlespacing*{\section}{0pt}{10ex}{6ex}

\begin{document}

\section{ This is what I'd like to have}

\section{This is also what I'd like to have}

\end{document} 

Answer 2

我建议坚持使用基本标记，因为它允许您在将来以全局（简单）的方式更改事物，而不必找到每个\begin{center}...\end{center}构造来更改某些内容。

下面我使用sectsty更改章节标题的格式/样式并删除章节编号。这样，\section{...}仍然可以防止在页面底部被孤立，同时您的center构造可能会与其内容分离。

\documentclass{article}

\usepackage{sectsty}
\sectionfont{\normalfont\large}% Section font styling
\makeatletter
\renewcommand{\@seccntformat}[1]{}% Remove section numbering
\makeatother

\begin{document}

\section{This is what I'd like to have}
