# Colored fancy boxes

I am trying to produce some fancy boxes. I have found the fancybox package that does the boxes I want.

What I can't find now is: How do I change their background color?

I would also like to make the box occupy the whole \textwidth.

Can anyone help?

You mean the fancybox (not fancyboxes) package? It does not support colors by itself.

I would use the framed package together with xcolor to define the fancy box you want. If you do not require special stuff like verbatim material you could simply go with:

\usepackage{xcolor}
% ...
\fcolorbox{<frame color>}{<background color>}{\parbox{\textwidth}{%
\color{<text color>}%
<text>
}}


Otherwise define an own framed environment. Then the box will be \textwidth wide by itself. It even support page break, i.e. splits over multiple pages if the internal text does.

\usepackage{xcolor}
\usepackage{framed}

\newenvironment{myfancybox}{%
\def\FrameCommand{\fboxsep=\FrameSep \fcolorbox{<frame color>}{<background color>}}%
\color{<text color>}\MakeFramed {\FrameRestore}}%
{\endMakeFramed}

Sorry, I did meant fancybox. I have managed what I wanted with the sectionbox package. Does framed allow for shadowbox? –  Tiago Veloso Feb 2 '11 at 9:28
@Tiago: It support all boxing macros. Just redefine \FrameCommand accordantly. –  Martin Scharrer Feb 2 '11 at 9:50

use package mdframed the boxes can also have a pagebreak inside

The link is broken, here is one that works (for now) ctan.mirrorcatalogs.com/macros/latex/contrib/mdframed/… –  AD. Oct 8 '13 at 19:58

For those who are (almost) complete beginners and want something they can directly use I stumble upon the "tcolorbox" package, here is a tutorial
