Okay. I understand that I should put this code:
—————————————————————–
add_filter( ‘wp_trim_excerpt’, ‘tu_excerpt_metabox_more’ );
function tu_excerpt_metabox_more( $excerpt ) {
$output = $excerpt;
if ( has_excerpt() ) {
$output = sprintf( ‘%1$s <p class=”read-more-button-container”>%3$s</p>’,
$excerpt,
get_permalink(),
__( ‘Read more’, ‘generatepress’ )
);
}
return $output;
}
————————————————————
But where should I put it? Under “Customization > Additional CSS?” or in “Elements > Hook”?
