how to customise popupex.css ?

Hi

How is-it possible to customise /modules/mod_uddeim/popupex.css without hack this css file..

I have made a new template in /components/com_uddeim/template but i don't find how to cutomise the modules's css.

Regards.

I answer to me (partial answer).

i put a class suffix and a modifiy my general template with (p.e.) :

.moduletable_myclass_sufx #floaterDiv {
border: 2px ridge #F0F0F0;
position: fixed;
width: 150px;
height: 120px;
left: -400px;
top: 20px;
background-color: #646464;
text-align: center;
z-index: 10000;
color: #000000;
}

I cannot find how to link the module style to my uddeim template.
