CSS is intentionally omitted.
Evidently you need more CSS fu.
Try something like this:
/* Column Classes */
.column-clearfix {clear: both;}
.column-wrapper-2 .column {
height:100%;
float: left;
margin: 0 1.5%;
width: 47%;
background: url(../img/division.gif) right repeat-y;
}
.column-wrapper-2 .column-first {}
.column-wrapper-2 .column-last {
background-image: none !important;
}
.column-wrapper-2 .column-1 {}
.column-wrapper-3 .column {
height:100%;
float: left;
margin: 0 1.5%;
width: 29%;
background: url(../img/division.gif) right repeat-y;
}
.column-wrapper-3 .column-first {}
.column-wrapper-3 .column-last {
background-image: none !important;
}
.column-wrapper-3 .column-1 {}
Also try changing the plugin settings to use before and after marks (Normal content before … after … separator), and in the CSS example above you would need to change the CSS Column Class Prefix.
