Text left spacing (local “margin”) [duplicate]

Question

How can I add left space to a block of text? (see the attempts and pictures below)

I can think of two ways:

minipage

\documentclass{article}

\usepackage{lipsum}

\begin{document}

\lipsum[1]

\noindent
\hspace{2em}%
\begin{minipage}{0.95\textwidth}
\lipsum[2-3]
\end{minipage}

\end{document}

Three problems:

1. I cannot use another minipage within that minipage (which I need in my usecase)
2. Indentation and paragraph spacing seem to change
3. What to pass as the width optional argument?

enumitem

Using itemize with the enumitem options:

\documentclass{article}

\usepackage{lipsum}
\usepackage{enumitem}  % needed!

\begin{document}

\lipsum[1]

\begin{itemize}[label={},leftmargin=2em]
\item \lipsum[2-3]
\end{itemize}

\end{document}

It loses indentation and the paragraph spacing is a little different than the rest, but looks like much better:

Anyhow, any other suggestion?

Answer 1

Here is a suggestion using the addmargin environment defined by package scrextend.

\documentclass{article}
\usepackage{lipsum}
\usepackage{scrextend}
\begin{document}
\lipsum[1]
\begin{addmargin}[2em]{0em}
\lipsum[2-3]
\end{addmargin}
\end{document}

Note that scrextend is a package to use some KOMA-Script Features like addmargin with other classes. Hence if you use a KOMA-Script class there is no need to load scrextend.

Answer 2

Considering @touhami's comment and this answer from another question, here is a MWE that uses two other approaches for local paragraph margins:

\documentclass{article}

\usepackage{lipsum}

% \adjustwidth
\usepackage{changepage}

% https://tex.stackexchange.com/a/600/34244
%\def\changemargin#1#2{\list{}{\rightmargin#2\leftmargin#1}\item[]}
%\let\endchangemargin=\endlist

% touhaim's suggestion:
\def\changemargin#1#2{\list{}{%
\setlength{\leftmargin}{#1}%
\setlength{\rightmargin}{#2}%
\setlength{\topsep}{0pt}%
\setlength{\parsep}{\parskip}%
\setlength{\itemindent}{\parindent}%
\setlength{\listparindent}{\parindent}%
}\item[]}

\begin{document}

\lipsum[1]

\begin{adjustwidth}{4cm}{4cm}
\lipsum[2]
\end{adjustwidth}

\lipsum[3]

\begin{changemargin}{4cm}{4cm} 
\lipsum[4]
\end{changemargin}

\lipsum[5]

\end{document}
