Grey box around the text

Question

I have to write a newenvironment, which plots a grey box around the text.

I can't decide which package I should be use. I am writing a dissertation and I want that some text sections have a grey box around the text.

Which package should I use for my newenvironment{greyBox}?

So you see down newenvironment it produces grey box around my text, but I want use this one

\vspace{5mm}
\begingroup
\leftskip4em
\rightskip\leftskip\textit{``text here.''}
\vspace{5mm}
\endgroup

in my newenvironment, but i can't integrate into it. The text in newenvironment should to intend right and left.

\documentclass{book}
\usepackage[ngerman]{babel} 
\usepackage{xcolor}
\usepackage{mdframed}

\newenvironment{bla}%
  {\begin{mdframed}[backgroundcolor=lightgray]}%
  {\end{mdframed}}

  %%%%%%%%%%%%%%%%%%%

\begin{document}

\begin{bla}

\begin{itemize}

 \item Beccari 
 \item Gregorio  
\item Blue  

\end{itemize}
\end{bla}

\end{document}

I want exactly, that text + box are centered.

I want like this picture enter image description here

Only the red part should be have a grey box, but I don't find still yet a solution.

You might want to look into the mdframed package, that could do this for you. — Chris H, Oct 14 '13 at 10:59
Can I change this example in newenvironment. \usepackage{color} \definecolor{lightgray}{gray}{0.75}
\newcommand\greybox[1]{% \vskip\baselineskip% \par\noindent\colorbox{lightgray}{% \begin{minipage}{\textwidth}#1\end{minipage}% }% \vskip\baselineskip% } — blue, Oct 14 '13 at 10:59
you might want to edit your question to put the code from your comment into it, formatted as block code - it would be much easier to follow. — Chris H, Oct 14 '13 at 11:01
I'm sure it will be up soon, but googling mdframed manual should get you a copy of the manual from elsewhere. — Chris H, Oct 14 '13 at 11:02
You might wanna check these topics: framed or mdframed and tcolorbox or mdframed. — masu, Oct 14 '13 at 11:08
Marking up blocks of code can be a little tricky, I edited your question to help out, but you should use the preview pane in the future to make sure your post looks like you want it to. — StrongBad, Oct 14 '13 at 12:24
@cmhughes thank you for this example but this is for theorem, but I will try it. — blue, Oct 14 '13 at 16:31
@Harish Kumar I solved the problem different with mdframed, but your example is really well. Thank you for this. I have to decide which one I use at last. — blue, Oct 16 '13 at 10:32
@Harish Kumar I tried something and notice that the colorbox jump on the other page, when the box don't suit on the page, but I don't want this. When the box don't suit on the page then it should be separate in the other page. I hope you understand me. — blue, Oct 16 '13 at 11:02
