Thanks Christian, I got everything working like I wanted. I set it up to load the side.css theme. The only change I would like to make is have the PDF and link icons like in the default.css. However I think the .bibbase_icon { display: none; } that is loaded in side.css prevents the icons from being loaded (when I toggle that off in chrome the icons show up with the size I want). To fix this I set bibbase_icon to display: inline-block; and now I get the side theme with the link and pdf icons like I wanted.
