頁邊空白中的段落問題

Question

我正在為我的班級寫一些論文，並希望將任務編號為兩到三個級別。第一級應該是一個簡單的數字，如 1)，而下一級應該用數字標記。看著這個問題如何在頁邊空白處對段落（和章節）進行編號？它幾乎滿足了我的需要。我嘗試自己改變數字，但遇到了一些困難。

正如人們所看到的，第一個小段被跳過並被替換為 )。我不知道我的程式碼是否是最好的，如果有人有更好的方法來獲得類似的輸出，我會很高興聽到它。我發現將 \section 和 \subsection 等級與 \paragraph 等級混合有點奇怪。

\usepackage{amssymb,mathtools}      % Matematikk.
\usepackage{enumitem}                        % Mer muligheter for lister

\setcounter{secnumdepth}{5}
\renewcommand\thesection{\bfseries\small\arabic{section})}

% this length controls tha hanging indent for titles

\setlength\titleindent{1cm}

\pretocmd{\paragraph}{\stepcounter{subsection}}{}{}
\pretocmd{\subparagraph}{\stepcounter{subsubsection}}{}{}

\newcounter{problem}[section]

\renewcommand{\theproblem}{\bfseries\small\alph{problem})}

\begin{document}

\paragraph{}
Given an element $x$, $x_v$ is its value and $x_s$ its unit. 
Let the set $D$ be a standard deck of $52$ cards. 

\subparagraph{} 
Find the cardinality of the following sets:
\begin{enumerate}[leftmargin=*]
\item $S = \left\{ x \in D \mid x_s = \text{spades} \right\}$
\item $B = \left\{ \text{the set of court cards in } D \right\}$
\item $S \cap B$
\item $S \cup B$
\item $S\,\backslash\,B$
\item $S \times B$
\item $\left\{ (x,y) \in D \times D \mid x = y \right\}$
\end{enumerate}

\subparagraph{} 
Fill in the correct symbol $\in,\,\subseteq\,\, \nsubseteq$

\begin{enumerate}[leftmargin=*]
\item ace of hearts
\item ace of hearts
\item S D
\item S B
\end{enumerate}

\subparagraph{Fee fuu foo}

我真的不明白為什麼你使用section段落計數器和subsection分段計數器以及新計數器problem；這是一種變體，其中每個分區單元使用其自然計數器並且不需要額外的計數器：

\documentclass[10pt,a4paper]{article}
\usepackage{amssymb,mathtools}
\usepackage{enumitem}
\usepackage{titlesec}

\setcounter{secnumdepth}{5}

% this length controls tha hanging indent for titles
% change the value according to your needs
\newlength\titleindent
\setlength\titleindent{1cm}

\renewcommand\theparagraph{\bfseries\small\arabic{paragraph})}
\renewcommand\thesubparagraph{\bfseries\small\alph{subparagraph})}

\titleformat{\paragraph}[runin]
  {\normalfont\large}{\llap{\parbox{\titleindent}{\theparagraph\hfill}}}{0em}{}

\titleformat{\subparagraph}[runin]
  {\normalfont\large}{\llap{\parbox{\titleindent}{\thesubparagraph\hfill}}}{0em}{}

\titlespacing*{\paragraph}{0pt}{3.25ex plus 1ex minus .2ex}{0em}
\titlespacing*{\subparagraph}{0pt}{3.25ex plus 1ex minus .2ex}{0em}

\setlist[enumerate]{leftmargin=*}

\begin{document}

\item $S \cap B$
\item $S \cup B$
\item $S\,\backslash\,B$
\item $S \times B$
\item $\left\{ (x,y) \in D \times D \mid x = y \right\}$
\end{enumerate}

\subparagraph{} 
Fill in the correct symbol $\in,\,\subseteq\,\, \nsubseteq$

\begin{enumerate}

\item ace of hearts

\end{enumerate}

\subparagraph{Fee fuu foo}

\end{document}

如果您不打算使用分段單位的參數，那麼僅使用分段單位來實現編號似乎是「不自然的」；這是程式碼的新變體，不使用分段單元，而是使用使用套件定義的新的類似清單的環境enumitem：

\documentclass[10pt,a4paper]{article}
\usepackage{amssymb,mathtools}
\usepackage{enumitem}
\usepackage{titlesec}

\newlength\titleindent
\setlength\titleindent{1cm}

\newlist{problem}{enumerate}{3}
\setlist[problem,1]{label=\textbf{\arabic*)},leftmargin=0pt,labelsep=\titleindent,itemsep=3.25ex}
\setlist[problem,2]{label=\textbf{\alph*)},leftmargin=0pt,labelsep=\titleindent,itemindent=-7pt,itemsep=3.25ex}
\setlist[problem,3]{label=\arabic*.,leftmargin=\dimexpr\titleindent-20pt\relax,labelsep=10pt}

\begin{document}

\begin{problem}
\item Given an element $x$, $x_v$ is its value and $x_s$ its unit. 
Let the set $D$ be a standard deck of $52$ cards. 

  \begin{problem}

    \item $S \cup B$
    \item $S\,\backslash\,B$
    \item $S \times B$
    \item $\left\{ (x,y) \in D \times D \mid x = y \right\}$
    \end{problem}

  \item Fill in the correct symbol $\in,\,\subseteq\,\, \nsubseteq$

    \begin{problem}
    \item ace of hearts
    \item ace of hearts
    \item S D
    \item S B
