漂亮的部分样式

Question

我偶然发现了伊雷姆我在以下文件中发现了漂亮的部分样式原始文件是用 PDFLaTeX 创建的。

有人可以用 Latex 创建章节和小节的样式吗？

\documentclass{article}
\usepackage[utf8]{inputenc}

\title{Sections and Chapters}
\author{Educ}
\date{\today}

\begin{document}

\maketitle

\section{Plya's Problem-Solving Cycle}
\subsection{Understand the problem}
\subsection{Devise a Plan}
\subsection{Carry Out the Plan}
\subsection{Look Back}
\section{Second Section}


\end{document}

Answer 1

答案基于titlesec和soul：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{xcolor}
\usepackage[explicit]{titlesec}
\usepackage{soul}

\definecolor{titleblue}{HTML}{4a7aa4}

\title{Sections and Chapters}
\author{Educ}
\date{\today}

\newbox\TitleUnderlineTestBox
\newcommand*\TitleUnderline[1]
  {%
    \bgroup
    \setbox\TitleUnderlineTestBox\hbox{\colorbox{titleblue}\strut}%
    \setul{\dimexpr\dp\TitleUnderlineTestBox-.3ex\relax}{.3ex}%
    \ul{#1}%
    \egroup
  }
\newcommand*\SectionNumberBox[1]
  {%
    \colorbox{titleblue}
      {%
        \makebox[2.5em][c]
          {%
            \color{white}%
            \strut
            \csname the#1\endcsname
          }%
      }%
    \TitleUnderline{\ \ \ }%
  }
\titleformat{\section}
  {\Large\bfseries\sffamily\color{titleblue}}
  {\SectionNumberBox{section}}
  {0pt}
  {\TitleUnderline{#1}}
\titleformat{\subsection}
  {\large\bfseries\sffamily\color{titleblue}}
  {\SectionNumberBox{subsection}}
  {0pt}
  {\TitleUnderline{#1}}

\begin{document}

\maketitle

\section{Plya's Problem-Solving Cycle}
\subsection{Understand the problem}
\subsection{Devise a Plan}
\subsection{Carry Out the Plan}
\subsection{Look Back}
\section{Second Section}

\section

\end{document}
