Logo and Descriptiom

How do I hide the logo and description to twenty nineteen?

<div class=”site-branding”>

<?php if ( has_custom_logo() ) : ?>
<div class=”site-logo”><?php the_custom_logo(); ?></div>
<?php endif; ?>
<?php $blog_info = get_bloginfo( ‘name’ ); ?>
<?php if ( ! empty( $blog_info ) ) : ?>
<?php if ( is_front_page() && is_home() ) : ?>
<h1 class=”site-title”>” rel=”home”><?php bloginfo( ‘name’ ); ?></h1>
<?php else : ?>
<p class=”site-title”>” rel=”home”><?php bloginfo( ‘name’ ); ?></p>
<?php endif; ?>
<?php endif; ?>

<?php
$description = get_bloginfo( ‘description’, ‘display’ );
if ( $description || is_customize_preview() ) :
?>
<p class=”site-description”>
<?php echo $description; ?>
</p>
<?php endif; ?>
