Thanks, Mark. It worked. I added the entire code to Custom CSS provided by the Jetpack plugin and reduced the font size to 20px. It looks much better – the same size as the title size on the pages.
Tara, I posted this problem here because the theme’s developer did not respond. Expound is a free theme, not commercial and as such does not provide support. You can only email or tweet the developer. Anyhow, Mark found the relevant CSS code that I failed to find using the Firefox Firebug add-on.
