I would like that second column ‘Naslov opomba’ is the same height than ‘Naslov besedilo’.

I tried to set all a CSS property of height: 100%, but the right-column still does not adjust the height.

<div id=”wrapper-columns” style=" height: 100%;">
<div id="left-column" style=" height: 100%;">
<p>Naslov besedilo. …</p>
<div id="right-column" style=" height: 100%;">
<p>Naslov opomba. …</p>

How to set right-column to be same height as content in left-column?

Thanks for help.
