# How to create three column document with visible dividers?

I added \threecolumn but it doesn't work.

What command will change the document layout to three column format with dividers visible like the following illustration?

---------HEADER---------
###### | ###### | ######
###### | ###### | ######
###### | ###### | ######
###### | ###### | ######
###### | ###### | ######
###### | ###### | ######

You can use the multicol package to do this. It's manual is typeset in three column format! (at least the first half). A separation line can be added by setting the \columnseprule length.

\documentclass{article}

\usepackage{multicol}
\usepackage{lipsum}% dummy text

\setlength{\columnseprule}{0.4pt}

\begin{document}
\begin{multicols}{3}

\section{Test}
\lipsum
\section{Test}
\lipsum
\section{Test}
\lipsum

\end{multicols}
\end{document}

Thank you for the hint. I am using pictures with \includegraphics[width=1.0\textwidth] and they are not handled correctly with multicol which renders the package unusable for me. Is there another package or a workaround for this issue? – gentlesea Mar 4 at 8:34
\documentclass[a5paper]{article}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{multicol}
\setlength\columnseprule{0.5pt}
\begin{document}

\begin{multicols}{3}
\blindtext
\end{multicols}

\end{document}
