<?php echo $args['before_widget']; ?> 

    <div class="page-box  page-box--<?php echo esc_attr( $instance['layout'] ); ?>"> 
        <?php 
        if ( $page['thumbnail'] ) : 
            if ( 'block' === $instance['layout'] ) : 
        ?> 
            <a class="page-box__picture" href="<?php echo esc_url( $page['link'] ); ?>"> 
                <img src="<?php echo esc_url( $page['image_url'] ); ?>" width="<?php echo esc_attr( $page['image_width'] ); ?>" height="<?php echo esc_attr( $page['image_height'] ); ?>" srcset="<?php echo esc_attr( $page['srcset'] ); ?>" sizes="(min-width: 992px) 360px, calc(100vw - 30px)" class="wp-post-image" alt="<?php echo esc_attr( $page['post_title'] ); ?>">
