How to remove the blind affect on submenu

I’m not sure what you mean by “blind” effect? Are you referring to how it opens up when you hover? If so, I think that has something to do with the superfish/javascript that is used in the Genesis Framework. It shows up that way by default. Example – https://demo.studiopress.com/genesis-sample/

Try adding this code in your functions file –

add_action( 'wp_enqueue_scripts', 'sp_disable_superfish' );
function sp_disable_superfish() {
    wp_deregister_script( 'superfish' );
    wp_deregister_script( 'superfish-args' );
}

To remove the Parallax effects, take a look in your front-page.php file and Comment Out or Remove this code –

//* Enqueue parallax script
add_action( 'wp_enqueue_scripts', 'guru_enqueue_parallax_script' );
function guru_enqueue_parallax_script() {

  if ( ! wp_is_mobile() ) {

    wp_enqueue_script( 'parallax-script', get_bloginfo( 'stylesheet_directory' ) . '/js/parallax.js', array( 'jquery' ), '1.0.0' );

  }

}

The background images will still be in a fixed position, but the Parallax effect will be disabled. If you want to ALSO remove the fixed background images then you’ll need to look at line 1456 or search for this –

.front-page-1,
.front-page-3,
.front-page-5,
.front-page-7,
.front-page-9,
.front-page-11 {
	background-attachment: fixed;
	background-position: 50% 0;
	background-repeat: no-repeat;
	-webkit-background-size: cover;
	-moz-background-size:    cover;
	background-size:         cover;
}

…then comment out or remove this part – background-attachment: fixed;

You’re Welcome!
