Multiline figure caption centering

Question

How to center a figure caption that's too long for a single line? Or at least, make the text in other lines line-up with text after "Slika 1:". It currently looks like this

Answer 1

Use the caption package.

\documentclass{article}

\usepackage[justification=centering]{caption}% or e.g. [format=hang]

\begin{document}

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This caption is very long---in fact, it is so long that it doesn't fit on one line}
\end{figure}

\end{document}
