(We just got another question asking for something similar: Quote style like on owni.eu. I wasn't aware of this question when I started to answer that one, but on becoming aware of it decided to post my answer here instead.)

It's also TikZ-based but slightly different to Alan's as the whole thing ends up in a TikZ node. This does mean that it won't work with page-breaking. One could also adapt the quote marks from Alan's version to make them look a bit better.

Here's the result:

And here's the code:

documentclass{article}

usepackage{lipsum}

Had I known about this question, I would not have written cfr-dquote. However, I didn't, so I did. Here's a lightly modified version of my package for public consumption or rejection.

The package defines a command, dquote[<dimension>]{<long text>}{<short text} which is intended to be used so that <dimension> is the width desired, <long text> is the quotation and <short text> is the attribution.

The package is based on TikZ and the appearance can be customised using the usual key-value interface. For example, I've never used this with a coloured background to the quotation, but that is easy to achieve by simply altering quote style.

For example,

documentclass[a4paper,british]{article}

usepackage[utf8]{inputenc}

usepackage{geometry,babel,csquotes}

usepackage{cfr-lm}

usepackage{cfr-dquote}

MakeAutoQuote{‘}{’}

MakeAutoQuote*{“}{”}

begin{document}

tikzset{%

  dquote text font=fontfamily{LobsterTwo-LF}selectfontLargeupshape,

  dquote attrib font=fontfamily{LobsterTwo-LF}selectfontHugeitshape,

  dquote={

    quote style/.style={align=justify, fill=blue!50!cyan, fill opacity=.2, text opacity=1, text=blue!15!darkgray},

    marks={

      size=Huge,

      scale=4,

      color=blue!50!darkgray,

      opacity=.5,

    },

  },

}%

dquote{%

  ‘Come, we shall have some fun now!’ thought Alice. ‘I'm glad they've begun asking riddles --- I believe I can guess that,’ she added aloud.



  ‘Do you mean that you think you can find out the answer to it?’ said the March Hare.



  ‘Exactly so,’ said Alice.



  ‘Then you should say what you mean,’ the March Hare went on.



  ‘I do,’ Alice hastily replied; ‘at least --- at least I mean what I say --- that's the same thing, you know.’



  ‘Not the same thing a bit!’ said the Hatter. ‘Why, you might just as well say that ‘I see what I eat’ is the same thing as ‘I eat what I see’!’



  ‘You might just as well say,’ added the March Hare, ‘that ‘I like what I get’ is the same thing as ‘I get what I like’!’



  ‘You might just as well say,’ added the Dormouse, which seemed to be talking in its sleep, ‘that ‘I breathe when I sleep’ is the same thing as ‘I sleep when I breathe’!’

produces the following output

The package consists of two files, cfr-dquote.sty and cfr-dquote.tex. In theory, the latter can be compiled alone, since it uses the standalone class, but don't be tempted to use it this way - that's just to make tweaks and debugging easier.

I know that this is old, but I may as well share my simple attempt.

Note: requires usepackage{xcolor}

The command itself:

newcommand{quotebox}[1]{begin{center}fcolorbox{white}{blue!15!gray!15}{begin{minipage}{0.9linewidth}vspace{10pt}centerbegin{minipage}{0.8linewidth}{spaceHuge``}{#1}{hspace{1.5em}breaknullHugehfill''}end{minipage}smallbreakend{minipage}}end{center}}

Minimum working example:

documentclass{article}

usepackage{xcolor}

newcommand{quotebox}[1]{begin{center}fcolorbox{white}{blue!15!gray!15}{begin{minipage}{0.9linewidth}vspace{10pt}centerbegin{minipage}{0.8linewidth}{spaceHuge``}{#1}{hspace{1.5em}breaknullHugehfill''}end{minipage}smallbreakend{minipage}}end{center}}

quotebox{Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth. Even the all-powerful Pointing has no control about the blind texts it is an almost unorthographic life One day however a small line of blind text by the name of Lorem Ipsum decided to leave for the far World of Grammar.}
