Add a Font Awesome icon to your post with this awesome standalone custom metabox.
Font Awesome gives you scalable vector icons that can instantly be customized — size, color, drop shadow, and anything that can be done with the power of CSS.
For developers it is easy to use the field in your theme. With the template functions the_fa() for echoing and get_ga() for returning the icon within the WordPress loop.
A handy Font Awesome shortcode is also included. Add an icon to your post by inserting [fa icon="fa-gear"], where the attribute is the name of the Font Awesome icon. You can also insert the current post icon by using the shortcode [fa].
