<div class="st-title-wrap">
<?php if( $sco || $sda || $sca ) : ?>
<aside class="s-info si-center clearfix">
<?php if( $sco ) : ?><a href="<?php comments_link(); ?>" rel="nofollow" class="com"><?php ac_icon('comment'); ?></a><?php endif; ?>
<?php if( $sda ) : ?><time class="date" datetime="<?php echo get_the_date( 'Y-m-d' ); ?>"><?php echo get_the_date( 'M d, Y' ); ?></time><?php endif; ?>
<?php if( $sca ) : ac_output_first_category( 'category' ); endif; ?>
</aside>
<?php endif; ?>
<?php the_title( '<h3 class="section-title st-wrapped st-large st-bold"><a href="' . esc_url( get_permalink() ) . '" rel="bookmark">', '</a></h3>' ); ?>
