Do not install this plugin on your WordPress site. It adds malicious js code including links to the infamous tracking site cc.chango.com. This site tracks users everywhere they go on the internet and CSS Plus adds code to every page or post, which includes the js code to contact the cc.chango.com site. Every page I tried to load from my site hung and waited as it tried to contact cc.chango.com before loading. I deactivated and deleted the CC Plus plugin and the malicious js code disappeared. DO NOT USE THIS PLUGIN!!!!!
