调整小节中的段落边距

Question

这可能是一个简单而又愚蠢的问题，但它困扰了我好几天。根据我的代码：

\documentclass[a4paper, 11pt]{article} 
\usepackage[margin=2cm]{geometry} % changes the margin
\usepackage{enumitem}
\usepackage{titlesec}
\usepackage{indentfirst}
\usepackage{blindtext}

\renewcommand\thesection{\Alph{section}.}
\renewcommand\thesubsection{\arabic{subsection}.}
\titleformat{\section}
{\normalfont\fontsize{11}{.5em}\bfseries}{\thesection}{.5em}
    {}
\titleformat{\subsection}
{\normalfont\fontsize{11}{.5em}\selectfont}{\thesubsection}{.5em}
    {}
\titlespacing % starred version: first paragraph is not indented
{\subsection} % <command>
{1em} % <left>
{.4em} % <before-sep>
{.3em} % <after-sep>

\begin{document}

\section{Introduction}
\subsection{Subsection One}
    \begin{itemize}  [leftmargin=1.3cm,topsep=0pt,itemsep=0pt,parsep=0pt,partopsep=0pt]
        \item some item here and there
        \item some item here and there
    \end{itemize}

\subsection{Subsection Two}
\setlength\parindent{.85cm} \blindtext

\end{document}

就得到了这张照片

我的问题是，如何调整与小节编号平行的段落边距？不是章节编号？

Answer 1

这是你想要的吗？这一切都依赖于\llap命令，它将其参数插入到行上当前点的左侧，而不移动后者。

\documentclass[a4paper, 11pt]{article}
\usepackage[margin=2cm]{geometry} % changes the margin
\usepackage{enumitem}
\usepackage{titlesec}
\usepackage{indentfirst}
\usepackage{blindtext}

\renewcommand\thesection{\Alph{section}.}
\renewcommand\thesubsection{\arabic{subsection}.}
\titleformat{\section}
{\normalfont\fontsize{11}{.5em}\bfseries}{\llap{\thesection\hskip0.67em}}{0em}
    {}
\titleformat{\subsection}
{\normalfont\fontsize{11}{.5em}\selectfont}{\thesubsection}{.5em}
    {}
\titlespacing % starred version: first paragraph is not indented
{\subsection} % <command>
{0em} % <left>
{.4em} % <before-sep>
{.3em} % <after-sep>

\begin{document}

\section{Introduction}
\subsection{Subsection One}
    \begin{itemize} [leftmargin=1.3cm,topsep=0pt,itemsep=0pt,parsep=0pt,partopsep=0pt]
        \item some item here and there
        \item some item here and there
    \end{itemize}

\subsection{Subsection Two}
\setlength\parindent{.85cm} \blindtext

\end{document}
