Plug-in CSS throws HUNDREDS of warnings

Hi –

Plug-in looks good and visually seems to function in 3.5.1. However, I went from a site that throws no warnings in the Console to HUNDREDS of warnings. Your CSS seems to have lots of problems. I am seeing this in Firebug – I’d like to attach the screen shot of a sample of the warnings, since I can’t seem to download them as a file, but attachments don’t seem to be allowed or I can’t find the tool. I’d be happy to email directly.

Plug-in is being used on this page:

(We may launch soon, so the “dev.” may go away on the URL)
