How to switch between two margin sizes?
As a young in LaTeX days now trying to find a solution to my problem. I try to use fullwidth command at tufte-book but because the text exceeds a page or two does not work. The only thing close to what I looking is How to switch between two different marginparwidth size? but again not what I want. Many many hours of research and nothing. I think and others will have the same problem please for some help
Thank you all for your immediate responses. Ι move a little late because I am new in latex and in English language. I trying to install mdframed under ubuntu to taste it. Here a small example of the problem:
\documentclass[a4paper,symmetric,twoside,nofonts,justified,marginals=raggedouter]{tufte-book}
\usepackage{lipsum}
\usepackage{multicol}
\begin{document}
\lipsum[1-3]
\begin{fullwidth}
\begin{multicols}{2}
\lipsum[1-5]
\end{multicols}
\end{fullwidth}
\end{document}
