Setup Whitelist body_class to Remove Unwanted Classes

Snippets by IsItWP

A whitelist is a great way to filter out many unwanted classes added in your theme. You can create a whitelist of the terms to include in body_class.

Instructions: Add the following code to the functions.php file of your WordPress theme to set up whitelist body_class.

add_filter('body_class', 'wps_body_class', 10, 2);

function wps_body_class($wp_classes, $extra_classes)
    // List of classes allowed
    $whitelist = array('portfolio', 'home', 'error404');

    $wp_classes = array_intersect($wp_classes, $whitelist);
    return array_merge($wp_classes, (array) $extra_classes);

You may also enjoy adding custom body_class using wp_is_mobile.
