Map popup balloon layout changes. HOW and WHERE?

Does anyone know how and where you can change the popup in the world map?

i've looked in the boonex/map/template/base/css but nothing.

is that div build up in js or php file?

I looked with Firebug but it return no css class name, just the element.

any help is welcome.

World map module popup templates:

modules/boonex/world_map/templates/base/popup_location.html - for single marker popup

modules/boonex/world_map/templates/base/popup_locations.html - for several markers at the same location popup

Thanx Alex but thats not it!! that only gives me the option to change the inner style but i want the outer style to change.

i can't find the file to change this! Look at attached image.

I did this with FireBug. Is this hard coded!!

Is there nobody that changed this also?

where is the style created for the div that is use for the popup balloon in the wmap?

This is default google maps balloon style, please refer to google maps api documentation to fint out if it is possible and how to change it:
