Hi Daniel-
You don’t need to modify the core BoldGrid files, you can actually use a filter in your child theme’s functions.php.
Here’s an article detailing the process of adding a custom social media icon. Specifically you’ll use a function and filter like this:
function add_custom_social_network_google( $networks ) {
$networks['google.com'] = array(
'name' => 'Google',
'class' => 'google',
'icon' => 'fa fa-google',
'icon-sign' => 'fa fa-google-square',
'icon-square-open' => 'fa fa-google fa-stack-1x',
'icon-square' => 'fa fa-google fa-stack-1x',
'icon-circle-open-thin' => 'fa fa-google fa-stack-1x',
'icon-circle-open' => 'fa fa-google fa-stack-1x',
'icon-circle' => 'fa fa-google fa-stack-1x',
);
return $networks;
}
add_filter( 'boldgrid_social_icon_networks', 'add_custom_social_network_google' );
