Webfonts plugin for themes
Heroic Webfonts allows you to customize your site fonts via the in-built WordPress theme customizer. No CSS knowledge required!
Use websafe fonts or webfonts from the google font library. You can also modify font color, size and style.
There are default styles the plugin supports (body and heading), which can be overridden by a supporting theme and you can add custom fonts with your own selectors and styles.
