How can I display Tags in each post

WP tags? Position?

Yes,under excerpt.

wp-content/plugins/recent-posts-widget-extended/includes/functions.php and extra code below line 204, excerpt section:

if ( $args['excerpt'] ) :
	$html .= '<div class="rpwe-summary">';
		$html .= wp_trim_words( apply_filters( 'rpwe_excerpt', get_the_excerpt() ), $args['length'], ' &hellip;' );
		if ( $args['readmore'] ) :
			$html .= '<a href="' . esc_url( get_permalink() ) . '" class="more-link">' . $args['readmore_text'] . '</a>';
		endif;
	$html .= '</div>';
endif;

tags (extra code):

$html .= '<span class="rpwe-tags">' . get_the_tag_list('<p>Tags: ',', ','</p>') . '</span>';

and additional css:

.rpwe-tags {
  font-size: 12px;
}

Thank you very much. ??
