You need to clearly define the core objectives of your website, the target audience, and the essential features it should have. The requirements for a photographer’s website that showcases a portfolio are vastly different from those of an e-commerce website that handles complex transactions and membership systems.

 Text Domain:  my-parent-theme-child

add_action( 'pre_get_posts', 'modify_main_query' );
function modify_main_query( $query ) {
    if ( ! is_admin() && $query->is_main_query() && $query->is_category('news') ) {
        $query->set( 'posts_per_page', 12 );
        $query->set( 'orderby', 'modified' );
        $query->set( 'order', 'DESC' );
    }
}
