jQuery licencing on commercial sites

jQuery licencing on commercial sites

I understand that any modified or derivative works are also MIT or GPL, however, if jQuery is called from a webpage on a commercial site, is the HTML that it is called from now a derivative work, and hence all the copyrighted content within is now also GPL or MIT?

What I'm trying to say is if jQuery is used on a commercial webpage, does the owner of the page now relinquish the copyrighted content of the page or site to the open license?

Thanks in anticipation.
