New Marker PopUp-Windows

In the sourcecode i found this div:
'<div id="contentInsertPlacemark">'

It seems like this div contains all the stuff where a user can enter informations for a new placemark, like title, description, placemarkgroup, etc.

How could i add a own css-class to that div?

Maybe i can put the div into a lightbox using a Spezial css.class and mondalizer from nonumber!

You can apply style direct by it's ID in your template

Right.

But to put that div in a lightbox using modalizer i Need a specific css-class like ".modalizer".

Normaly such css-class would be directly applied through a Suffix.
