Hi geogek !
You can do so by the following way:
open template_css.css file in ja_drimia/templates/ja_drimia/css folder , find following code section at about line 1825 :
#ja-masscol {
background:#FF760E url(../images/mc-bg.gif) no-repeat scroll 0%;
color:#FFFFFF;
display:block;
float:left;
height:130px;
margin-bottom:20px;
overflow:hidden;
position:relative;
width:40%;
}
change to :
#ja-masscol {
background:#FF760E url(../images/mc-bg.gif) no-repeat scroll 0%;
color:#FFFFFF;
display:block;
float:left;
height:130px;
margin-bottom:2px;
overflow:hidden;
position:relative;
width:40%;
}
