答案1

框架的默认宽度由\fboxrule（形状的代码frame可以在文件中找到frame.tts）给出，因此改变这个长度可以控制规则的宽度。

\color您可以通过在适当的位置插入命令来更改规则颜色（和字体颜色）\titleformat（参见下面的第一个示例）。

如需进一步自定义（例如添加阴影或颜色背景），我建议您使用tcolorbox包（见下面的例子）：

\documentclass{book}
\usepackage{xcolor}
\usepackage[explicit]{titlesec}
\usepackage[many]{tcolorbox}
\usepackage[english]{babel} 

\titleformat{\section}[frame] 
  {\setlength\fboxrule{3pt}\bfseries\itshape\fontsize{12.8}{14}\selectfont\color{red}}
  {}{5pt}
  {\color{black}$\;\;$\thesection\hskip 0.7em#1}

\begin{document}

\chapter{A test chapter}
\section{A test section}

\titleformat{\section}
  {\normalfont\bfseries\itshape\fontsize{12.8}{14}\selectfont}
  {}{0pt}
  {\begin{tcolorbox}[]\thesection\hskip0.7em#1\end{tcolorbox}}
\section{Another test section}

\titleformat{\section}
  {\normalfont\bfseries\itshape\fontsize{12.8}{14}\selectfont}
  {}{0pt}
  {\begin{tcolorbox}[
      enhanced,
      boxrule=0pt,
      arc=0pt,
      outer arc=0pt,
      interior code={\fill[overlay,cyan!30] (frame.north west) rectangle (frame.south east);},
    ]\thesection\hskip0.7em#1\end{tcolorbox}}
\section{Yet another test section}

\titleformat{\section}
  {\normalfont\bfseries\itshape\fontsize{12.8}{14}\selectfont}
  {}{0pt}
  {\begin{tcolorbox}[
      enhanced,
      boxrule=0pt,
      arc=0pt,
      outer arc=0pt,
      interior code={\shade[draw=black,left color=cyan!30,right color=orange!30] (frame.north west) rectangle (frame.south east);},
    ]\thesection\hskip0.7em#1\end{tcolorbox}}
\section{Yet another test section}

加载framed包后，我定义了一个frshaded可以完成这项工作的环境。正如您在序言中看到的那样，它可以用shadecolor和framecolor键以及和\FrameRule长度进行参数化\FrameSep：

\documentclass[11pt,a4paper,reqno,fleqn,x11names]{book} %
\usepackage[showframe]{geometry}
\usepackage{amsthm,amsmath,amsfonts} %
\usepackage{framed}
\usepackage[explicit]{titlesec} %
\usepackage[dotinlabels]{titletoc} % more advanced but essential here
\usepackage[english]{babel} %
\usepackage{xcolor}
\colorlet{shadecolor}{Thistle3!20!}
\colorlet{framecolor}{PaleVioletRed3}
\definecolor{darkblue}{rgb}{0,0.08,0.45}
\setlength\FrameRule{2pt}
\setlength\FrameSep{5pt}
\newenvironment{frshaded}{%
\def\FrameCommand{\fboxrule=\FrameRule\fboxsep=\FrameSep \fcolorbox{framecolor}{shadecolor}}%
\MakeFramed {\advance\hsize-\width \FrameRestore}}%
{\endMakeFramed}

\titleformat{\section} %
{\bfseries\itshape\fontsize{12.8}{14}\selectfont\color{Thistle4!80!}}
        {}{8pt}
{\begin{frshaded}\thesection\hskip 0.7em#1\end{frshaded}}

您可以使用fcolorbox：

\newlength{\mylen}
\settowidth{\mylen}{\hspace{\fboxsep}\thesection~}%

\titleformat{\section}%[frame] %
{\bfseries\itshape\fontsize{12.8}{14}\selectfont}
        {}{0pt}
{\fboxrule2pt\noindent\fcolorbox{red}{olive}{%
\parbox{\dimexpr\linewidth-2\fboxsep-2\fboxrule\relax}
{\hangindent=\mylen\hangafter=1 \thesection~#1}}}

这使
