# Removing horizontal space in enumerate

How can I remove the space between 1.1. and (1)?

Edit: @barbarabeeton's answer removes the space as required but I had a follow up question of whether there is a way to indent "Remark" with the body of the paragraph (1). Basically to have "Nullam" right below "Remark"in the following image:

MWE:

\documentclass[11pt]{amsart}
\usepackage[left=2cm,top=1cm,right=2cm,nohead,nofoot]{geometry}
\usepackage{amsmath, amssymb}
\usepackage{amsthm}
\usepackage[shortlabels]{enumitem}
\theoremstyle{plain}
\newtheorem{Theorem}{Theorem}[section]
\theoremstyle{definition}
\newtheorem{remark}[Theorem]{Remark}

\begin{document}
\section{A}
\begin{remark}
\begin{enumerate}[leftmargin=*]
\item ABC
\item ABC
\end{enumerate}
\end{remark}
\end{document}


• Like this (code)?

• remark is a theorem-class object. See this question: Annoying space before the first item in an enumeration which starts a theorem Jun 4, 2020 at 18:18
• @Werner Yes, the hack doesn't work for me. Since I label the list items and need to refer to them later. Jun 4, 2020 at 18:22
• @barbarabeeton I did use [leftmargin=*] after seeing that answer but there is still that little space left which is annoying. Jun 4, 2020 at 18:22
• I'll have to test that, but I have a meeting shortly, so it won't be possible for several hours. There's another approach, if you're willing to start the list on a new line: insert \leavevmode right after the \begin{remark}, or add a few words to provide some text. Jun 4, 2020 at 18:30

You may be interested in something a little more simplistic. Setting your own list-like environment:

\documentclass{amsart}

\usepackage{amsthm}
\usepackage{lipsum}

\theoremstyle{plain}
\newtheorem{Theorem}{Theorem}[section]
\theoremstyle{definition}
\newtheorem{remark}[Theorem]{Remark}

\newcounter{remarkitem}
\newenvironment{remarklist}{%
\setcounter{remarkitem}{0}% Restart counter
\setlength{\parindent}{0pt}%
\renewcommand{\item}{\par
\refstepcounter{remarkitem}%
\ifnum\value{remarkitem}=1
\hspace*{-0.5ex}%
\fi
\mbox{(\theremarkitem)}%
\nobreakspace
}
}{%
\par\addvspace{.5\baselineskip}%
}

\begin{document}

\section{A section}
See number~\ref{list:first} and~\ref{list:second}.
\begin{remark}
\begin{remarklist}
\item\label{list:first} \lipsum*[1]
\item\label{list:second} \lipsum*[2]
\end{remarklist}
\end{remark}

\end{document}

• But this still doesn't align the body of the paragraphs with "Remark". I would like to have "purus" right below "Remark" in your image. Jun 6, 2020 at 11:42
• @SahibaArora: So something like this?

• Yes exactly. How do I get that? Jun 6, 2020 at 17:13
• @SahibaArora: I've updated my answer with that detail. Note that you won't be able to use a nested list here. But I guess one can update that if necessary. It depends on the format.

• @SahibaArora: Yes. Use \renewcommand{\theremarkitem}{\alph{remarkitem}} somewhere after \newcounter{remarkitem}.
