Question

I’m writing an article for a magazine. I’m trying to insert a (floating) 2-column box at the upper right corner of a 3-column document, with the text wrapping around it nicely andn the columns being aligned. I’m making the box using the tikz package so I can have a box with rounded edges and a background color.
I was trying to do the wrapping using wrapfig (and I’ve tried some minipage stuff as well), but I can’t get it to work.

This is some code that explains what I’m trying to do, and how I’ve been trying to do it:

\documentclass{article}
\usepackage{wrapfig}
\usepackage{tikz}
\usepackage{multicol}

\definecolor{col}{rgb}{0.6,0.6,0.9}
\setlength{\columnsep}{0.5cm}
\newcommand{\floatingBox}[3]
{
 \noindent
 \begin{wrapfigure}{#1}{#2}
 \begin{tikzpicture}
 \node[rounded corners=5pt, fill=col, text width=\linewidth]{#3};
 \end{tikzpicture}
 \end{wrapfigure}
}

\begin{document}
\begin{multicols}{3}
\large
Some random rambling to fill a page.

\floatingBox{tr}{2\columnwidth + 1\columnsep}{
\begin{multicols}{2}
A box that spans 2 columns and should be floating on top of the page with 
the text wrapping around it.  It's aligned to the right, so it would be 
exactly above 2 entire columns, with one column to its left.
\end{multicols}

Answer 1

It is my experience that such layout (figure spanning more than one, but not all of the columns on the page) is difficult to obtain with latex.

The best solution that I’m aware of is the flowfram package. The package lets you define the page layout (where should certain boxes be placed) before writing the contents of the document.

A small code example is given below. It is a restructuring of the poster example that comes with the flowfram package.

\documentclass[a4wide]{article}

\usepackage{color}
\usepackage{helvet}
\usepackage{flowfram}

\setlength{\columnsep}{0.3cm}

% Base the page layout on 3 column with static header.
\NcolumnStop{3}{1 cm}
% give the static frame a label to make it easier to keep track of
\setstaticframe{\value{maxstatic}}{label={title},backcolor=[cmyk]{0.64,0,0.95,0.40},textcolor=white}

% On the first page, replace last two columns with
% 2 columns and a static above
\setflowframe{2,3}{pages={>1}}

\computeflowframearea{2,3}
\twocolumnStopinarea[1]{0.3\ffareaheight}{\ffareawidth}{\ffareaheight}{\ffareax}{\ffareay}
\setstaticframe{\value{maxstatic}}{label={info},backcolor=[cmyk]{0.26,0,0.76,0},clear}

\setallflowframes{backcolor=[cmyk]{0.15,0,0.69,0}}

\raggedright
\setlength{\parindent}{15pt}

\begin{document}
\begin{staticcontents*}{title}
\begin{center}
\bfseries\Large Creating stuff in \LaTeX\par
\end{center}
\end{staticcontents*}

\pagestyle{empty}

\begin{staticcontents*}{info}
\begin{staticfigure}

The {flowfram} package is designed to enable you to create
frames in a document such that the 
contents of the {document} environment flow from one 
frame to the next in the order that they were defined.  
This is useful for creating posters
or magazines or any other form of document that does not 
conform to the standard one or two column layout.

\end{staticcontents*}

This is a modified version of the manual for the {flowfram} 
package.  It is intended to illustrated what can be done. See the 
full manual (ffuserguide.pdf) for
a comprehensive description, as this may now be out of date. 
The commands used to define the frames for
this document are shown in Figure~\ref{fig:thisdoc}.
If the columns are very narrow, it may be better to
use {raggedright}, otherwise \TeX\ may have a
problem working out the line breaks.

\section{Introduction}

The {flowfram} package is designed to enable you to create
frames in a document such that the 
contents of the {document} environment flow from one 
frame to the next in the order that they were defined.  
This is useful for creating posters
or magazines or any other form of document that does not 
conform to the standard one or two column layout.

\section{Setting up Frames}

The {flowfram} package provides three types of frame:
{flow frames}, {static 
frames} and {dynamic frames}.

\subsection{Flow Frames}

The flow frame is the principle type of frame.
The text of the {document} environment will flow from 
one frame to the next in order of definition. Each 
flow frame has an associated width, height, 
position on the page, and optionally a border.

It is recommended that all the flow frames in a document
have the same width, otherwise problems may occur
when a paragraph spans to flow frames of unequal
widths. This is because \TeX's output routine does not
register the change in {hsize} until it reaches
a paragraph break. If it is absolutely necessary for 
flow frames to have unequal widths, judicious use of
{framebreak} is required.
