[Owncloud] CCS to give rightcontent a vertical scrollbar

[George Ruinelli]

How would I need to add a style to make the rightcontent of a template to have 
a vertical scrollbar if it is too high?
I would expect this is already handled in the core.css?
(I have not defined any other style jet for that page).

Below is a minimal example which should have a vertical scrollbar but doesn’t:
------------------------------------------
<div id="controls">Nothing here</div>
<div class="leftcontent">Nothing here</div>
<div class="rightcontent">
    A very long and height consuming text.<br>
    aa<br>
    ...<br>
    bb<br>
</div>
------------------------------------------
