Using Google Fonts as a Signature?

Hello,

I was wondering if there is an easy way to use Google Fonts plugin as a signature on a page.

Currently, I am using a transparent gif as a signature on the bottom of pages. I would like to use Google Fonts to create a signature. But I don’t want to change the font for the entire content (using <p> tag). Would I need to use one of the specific headings tag (h3, h4, h5) to make this work? Is there an alternative way to do this?

Thank you very much for your help! Wonderful plug-in, btw.
