# Enumeration indentation [duplicate]

I don't know, how this enumeration should be indented. It gives me the enumeration closely next to the word "Practice" and it should be on the separate line (under "Practice").

\documentclass[a4paper, 10pt]{article}
\usepackage{czech,amsmath,amsthm,amsfonts,multicol}
\topmargin0pt
\headheight0pt
\headsep0pt
\oddsidemargin0pt
\evensidemargin0pt
\setlength{\textwidth}{\paperwidth}
\addtolength{\textwidth}{-2in}
\setlength{\textheight}{\paperheight}
\addtolength{\textheight}{-2in}

\begin{document}
\theoremstyle{remark}
\newtheorem*{practice}{Practice}

\renewcommand{\labelenumi}{[\arabic{enumi}]}
\renewcommand{\labelenumii}{(\roman{enumii})}

\begin{practice}

\begin{enumerate}
\item ccc
\begin{enumerate}
\item fff
\item fff
\end{enumerate}
\item fff
\end{practice}
\end{document}

• Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Jun 28 '13 at 17:22
