This is my code in single.php:
<?php get_header(); ?>
<!– Begin Content –>
<div id=”content”>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?><?php if(function_exists(‘wp_print’)) { print_link(); } ?>
<div class=”post”>
<div class=”p-heading”><h1><?php the_title(); ?></h1></div>
<div class=”p-content”>
<?php the_content(); ?>
<?php wp_link_pages(array(‘before’ => ‘<p>Pages: ‘, ‘after’ => ‘</p>’, ‘next_or_number’ => ‘number’)); ?>
<?php the_tags( ‘<p>Tags: ‘, ‘, ‘, ‘</p>’); ?>
<?php edit_post_link(‘Edit this entry.’, ‘<p>’, ‘</p>’); ?>
<script async src=”//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js”></script>
<!– Responsive Ad –>
MY RESPONSIVE CODE
</script>
</div>
<div class=”p-info”><?php the_time(‘j.m.Y’) ?> | <?php the_category(‘, ‘); ?></div>
</div>
<div id=”content-a”>
Currently I have set code under all paragraphs at the end of each post, which is easy just add fixed code inside, but I would like if possible to add code without using any plugins to have under 3rd paragraph on each post.
