This page doesn't include the usual setup of js and css files of other NetrunnerDB pages. Instead, it includes only the files that some external page may want to include to add some features.

All the code from nrdb.*.js lives in the NRDB namespace and uses jQuery in noConflict mode (like this page).
Execute NRDB.tip.set_hide_event('unfocus') in the js console to have the tooltips stay on the screen. That should help you style them.
Warning: style.css adds styling to all .icon elements.div.qtip-nrdb div.qtip-content h4 p.card-info span.card-type span.card-keywords span.card-prop div.card-text p p p p.card-faction
