In my single wordpress posts I want to apply a padding of 100px to the left and right. The problem is that when I apply it to .single .post-content the images also get a padding. However, I want all of the images on the posts pages to be set to 100%. Is there a way to separate the actual body text and the images? This seems like a fairly simple question. But I can’t figure it out. Any help is appreciated.

single.php

<?php
get_header();
if (have_posts()) :
while (have_posts()) : the_post(); ?>
<article class="post">


        <?php $featuredImage = wp_get_attachment_url( get_post_thumbnail_id($post->ID), 'full' ); ?>
<div class="banner" style="background:url(<?php echo $featuredImage; ?>) no-repeat;"></div>



<?php wpb_set_post_views(get_the_ID()); ?>    
    <div class="post-info">    
    <h1 class="post-title"><?php the_title(); ?></h1>
   <h2 class="post-date"><?php echo strip_tags(get_the_term_list( $post->ID, 'location', 'Location: ', ', ', ' • ' ));?><?php the_date('F m, Y'); ?></h2>

    </div>
    <div class="post-content"><?php the_content(); ?></div>
    <div id="wrapper-footer"><div class="post-footer"><h1 class="post-footer-comment"><?php comments_popup_link ('No Comments', '1 Comment', '% Comments', 'post-footer-comment-count', 'none'); ?></h1><div class="share"><span>share</span> <?php get_template_part( 'share-buttons-post' ); ?></div></div>
        <div class="post-footer-bloglovin"><h1>never miss a post</h1><h2><a href="#">follow on email'</a></h2></div></div>
 <?php get_template_part( 'prevandnextpost' ); ?>
     <?php get_template_part( 'related-posts' ); ?>

<?php comments_template(); ?>
</article>
<?php endwhile;
else :
echo '<p>No content found</p>';
endif;
get_footer();

?>
