如何对一段文本进行特殊缩进

Question

这就是我需要的：

Headline
    First item in list
       continuation of description of first item if first line gets full
    second item on list
       continuation of description of item 2
       more continuation on item 2 if second line gets full as well

我基本上需要这个来记录一整章。我该如何制作这种特殊的列表？

Answer 1

此代码可能是解决方案...

\documentclass{book}
\usepackage{enumitem}
\usepackage[showframe, top=2.5cm, left=3.5cm, bottom=2.5cm, right=2.5cm, includehead]{geometry}

\begin{document}
\begin{description}
\item Headline
\begin{description}
  \item  First item in list\\
       continuation of description of first item if first line gets full
   \item   second item on list\\
       continuation of description of item 2
       more continuation on item 2 if second line gets full as well
\end{description}
\end{description}
\end{document}

Answer 2

\section*{Headline}

\noindent\hangindent3em  Bla bla bla ...

\noindent\hangindent3em  Bla bla bla ...

甚至

\section*{Headline}

{\parindent0pt
\parskip1ex
\everypar{\hangindent3em}

Bla bla bla ...\par
Bla bla bla ... \par}

但不要忘记使用花括号来限制命令的范围。
