"Read More" Bottom Button On Homepage Not Appearing After Content Bar Was Added To Top Of Page

I wanted to a add a black content bar with the title “Today’s Headlines” above my latest posts on my homepage and was told by a Design Wall staff member to : 
– go to Dashboard / Appearance / Customize / General Settings , and add this code below to custom wp_head

 <style>
.section-title {
text-transform: uppercase;
font-family: "NovecentowideNormalRegular",Georgia,"Times New Roman",Times,serif;
font-size: 11px;
padding: 0 20px!important;
background: #000;
color: #FFF!important;
margin: 30px 0 0!important;
border: none!important;
-webkit-border-radius: 0!important;
-moz-border-radius: 0!important;
border-radius: 0!important;
-webkit-box-shadow: -1px 0 0 #222 inset;
-moz-box-shadow: -1px 0 0 #222 inset;
box-shadow: -1px 0 0 #222 inset;
}
</style>

– Open file index.php in your site / wp-content / themes / your theme / index.php – Replace following code – form line 15 to line 28 

 <?php if( is_active_sidebar( 'dw_focus_home' ) ) { ?>
 <?php dynamic_sidebar('dw_focus_home'); ?>
 <?php } else { ?>
 <div>
 <?php while ( have_posts() ) : the_post(); ?>
 <?php get_template_part( 'content', 'archive' ); ?>
 <?php endwhile; ?>
 </div>
 <?php dw_focus_pagenavi(); ?>
 <?php } ?>

with

 <?php dynamic_sidebar('dw_focus_home'); ?>
<h3>Today’s Headlines</h3>
<div>
 <?php while ( have_posts() ) : the_post(); ?>
 <?php get_template_part( 'content', 'archive' ); ?>
 <?php endwhile; ?>
</div>

I followed these instructions and was successful in adding a content bar to my homepage but the "READ MORE" button at the bottom 
of the page no longer appears.  How can I get it back?

My homepage is set to "latest posts" in the readings section in WordPress's settings.
