Infinity Scroll doesn't display content correct with my theme

Hello,
I added the code in the functions.php file in the root directory of the Emphaino theme, but it still doesn’t work correctly.

add_action( 'after_setup_theme', 'emphaino_setup' );

add_theme_support( 'infinite-scroll', array(

    'container' 	=> 'dynamic-grid',

    'footer' 		=> true,

    'type'        	=> 'scroll',

    'posts_per_page' 	=> 6,

    'wrapper' 		=> false

) );

/**
 * Register widgetized area
 *
 * @since Emphaino 1.0
 */

Sadly I am not a web developer and my knowledge in the area is limited. I don’t know what to do. Any suggestions?
