How to display a content in two-column layout in LaTeX?

Use two minipages.

\begin{minipage}[position]{width}
  text
 \end{minipage}

Load the multicol package, like this \usepackage{multicol}. Then use:

\begin{multicols}{2}
Column 1
\columnbreak
Column 2
\end{multicols}

If you omit the \columnbreak, the columns will balance automatically.
