===== Custom Function Guideline ====

==== Share Parametter ====== parametter
1. $provider = select share provider. 
Example:
$provider = ['facebook', 'twitter', 'whatsapp'];

2. $attr = custom class, button style, 
$attr['class'] = 'class name';
$attr['style'] = 'style1';


Call custom function format:
if( function_exists('__wp_social_share') ){
    echo __wp_social_share( $provider, $attr );
}

if( function_exists('__wp_social_share_pro_check') ){
    if( __wp_social_share_pro_check() ){

    }
}
