Copied text is in original format, not destination format

Hello, I copied a quotation and a link that are in smaller font than I use to write, and instead of changing the font size to match my own font, it is keeping it small, in the original format.

I also copied a normal size post, and that is fine.

I tested this with another theme, and it doesn’t do this, so the problem is this theme.

What do I fix in this theme so it imports quotes, etc, in the font I’m currently using?

Thank you so much. http://www.donnabarstow.com/cartoon_blog/
