User blog:JayPryslack/ADMINS PLEASE LOOK AT THIS

So I think you should add these to the following pages: dev:ReferencePopups/code.js
 * Add This to MediaWiki:ImportJS
 * And Add This To MediaWiki:Common.css
 * (Also you should change the colours to match the wiki's theme)

.refpopups-box { background: none repeat scroll 0 0 #ffffff !important; border-color: #000000 !important; color: #000000 !important; font-size: 11px !important; }
