apply_filters( 'admin_body_class', string $classes )

Since
2.3.0
Filters the CSS classes for the body tag in the admin.

Description

This filter differs from the 'post_class' and 'body_class' filters in two important ways:

  1. $classes is a space-separated string of class names instead of an array.
  2. Not all core admin classes are filterable, notably: wp-admin, wp-core-ui, and no-js cannot be removed.
