Hi Emre,
Yes it works fine when the WC API Endpoint is ignored. 🙂
I have just installed Version 0.1.8 and css seem to use many common css classes. Including .clearfix. Additionally after a quick look into the css, i also find label, span, input, button.
If it must define its own clearfix i definitely agree with @davidsdesk that it uses a more plugin specific class.
I can see that @davidsdesk’s issue with .wrap still applies.
