Remove CSS from head

Hi,

Unfortunately there is no option for that. Usually minify/cache plugins are used to remove the stylesheets.

With a custom code it might be possible, but please be careful. Add this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!

function asl_remove_styles() {
    global $wp_filter;
    if ( isset($wp_filter['wp_head'], $wp_filter['wp_head']->callbacks, $wp_filter['wp_head']->callbacks[10]) ) {
        foreach ( $wp_filter['wp_head']->callbacks[10] as $k => &$f ) {
            if (
                isset($f['function']) &&
                is_array($f['function']) &&
                isset($f['function'][1])
            ) {
                if ( in_array($f['function'][1], array('StyleSheets', 'handle', 'inlineCSS')) ) {
                    unset($wp_filter['wp_head']->callbacks[10][$k]);
                }
            }
        }
    }

    if ( isset($wp_filter['wp_enqueue_scripts'], $wp_filter['wp_enqueue_scripts']->callbacks, $wp_filter['wp_enqueue_scripts']->callbacks[10]) ) {
        foreach ( $wp_filter['wp_enqueue_scripts']->callbacks[10] as $k => &$f ) {
            if (
                isset($f['function']) &&
                is_array($f['function']) &&
                isset($f['function'][1])
            ) {
                if ( in_array($f['function'][1], array('StyleSheets', 'handle', 'inlineCSS')) ) {
                    unset($wp_filter['wp_enqueue_scripts']->callbacks[10][$k]);
                }
            }
        }
    }
}
add_action( 'wp_head', 'asl_remove_styles', 100 );
add_action( 'wp_enqueue_scripts', 'asl_remove_styles', 100 );
add_action( 'init', 'asl_remove_styles' );

Best,
