The plugin is designed to naturally inherit the font that’s used on your website or WordPress theme so that it fits seamlessly into your site. You can manually change the font by just adding the following to the plugin’s Custom CSS section (which is on the plugin’s Customize page):
#cff{ font-family: sans-serif; }
Using Google Fonts in your feed
To use Google Fonts in your feed simply do the following:
1) Go to www.google.com/fonts and select the font you want to use
2) Select the @import option and copy and paste the code into the plugin’s Custom CSS section
3) Copy and paste the font-family code (shown in the screenshot below) into the following snippet and place it under the previous code in the plugin’s Custom CSS section:
#cff{ font-family: 'Open Sans', sans-serif; }
The entire code would look like this:
@import url(http://fonts.googleapis.com/css?family=Open+Sans);
#cff{ font-family: 'Open Sans', sans-serif; }
