# How can I use onecolumn and twocolmn text in different pages in the same document?

I am trying to use onecolumn and twocolumn, from the geometry package in the same document simultaneously (that is, different styles in different pages).

Is there any way to achieve that?

• use \onecolumn or \twocolumn to switch Aug 5 at 15:28

One way is to use multicols environment (from multicol, see documentation) and change document's layout in-place

\documentclass{article}
\usepackage{multicol}
%%% Added only for dummy texts and can be removed
\usepackage{kantlipsum}
%%% END

\NewExpandableDocumentCommand\ctitle{O{l}m}{%
\multicolumn{1}{@{}#1}{\textcolor{blue}{\textsc{#2}}}}

\begin{document}
\section{One-column layout}
\kant[1]

\begin{multicols}{3}[\section{Mult-icolumn layout}]
\kant[2]
\end{multicols}
\kant[3][1-2]

\section{One-column layout}
\kant[4]
\end{document}
