Main widget : height 0px;

This css property cause problems in the main website, and probably in others : the widget does not appear at all.

height: 0px; is the right syntax.
I don't locate the problem.

The problem here is that we use a disgusting hack to print the widget on the page to set the widget. Try commenting lines 81 and 82 in programme/web/kalendarium/templates/kalendarium/widget.html and see what happens.
Last time I did that, the widget wasn't printed.
