backgroundsboxescolor
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?
Here a way to define such a box using adjustbox. See the manual for more options.

Best Answer
You mean the
fancybox(notfancyboxes) package? It does not support colors by itself.I would use the
framedpackage together withxcolorto define the fancy box you want. If you do not require special stuff likeverbatimmaterial you could simply go with:Otherwise define an own
framedenvironment. Then the box will be\textwidthwide by itself. It even support page break, i.e. splits over multiple pages if the internal text does.
