Dear ROb!
Here is the solution to resolve your issue!
1) add the following style into the template.css file:
.mystyle{
border:#D5D5D5 solid 1px;
}
.mystyle h3{
background:url(“../images/h3-bg.gif”) repeat-x scroll left bottom transparent;
border-bottom:1px solid #A5A5A5;
color:#656565;
font-size:100%;
margin:0 0 10px!important;;
overflow:hidden;
padding:10px!important;
text-shadow:1px 1px 0 #FFFFFF;
text-transform:uppercase;
}
.mystyle .ja-box-ct {
margin:0 10px 20px!important;
}
2) please download this image: http://templates.joomlart.com/ja_seleni/templates/ja_seleni/images/h3-bg.gif and put it into the /templates/ja_urani/images folder
3) in the main menu module please put the ” mystyle” (note: add a blank before this text) into the Module Class Suffix parameter
GOod luck
