guest-class

If you want WordPress to automatically append a class to the body_class list when users are not authenticated, put that class name here.

Usage

Key	Type	Required	Default
`"guest-class"`	`string`	No	`"guest"`

To remove this functionality altogether, set to "null"

<?php # config.php
return [
    "guest-class" => "my-custom-class",
]

Also note that we must call the body_class() (or get_body_class()) function to get these classes wherever our body tag is located in the theme.

<!-- header.php -->
<?php wp_head() ?>

<body <?php body_class() ?>>
