Hi,

This code is added by Redux Framework plugin to apply settings styles from the dashboard. Unfortunately, there is no option to remove them or move to the file since they are always generated dynamically. If you want, you can do this with additional code customization.

1. Copy the whole code between <style></style> tags to the child theme style.css file.

2. Edit the file wp-content/plugins/redux-framework/ReduxCore/framework.php end remove this line

add_action( 'wp_head', array( &$this, '_output_css' ), 150 );

Regards
