Thank you so much!! I did try to search the subject but link and your code there was perfect!
<div class="fb-comments"data-href="<?php the_permalink(); ?>" data-num-posts="2" mobile="false"></div>
<style>.fb-comments, .fb-comments iframe[style], .fb-like-box, .fb-like-box iframe[style] {width: 100% !important;}
.fb-comments span, .fb-comments iframe span[style], .fb-like-box span, .fb-like-box iframe span[style] {width: 100% !important;}
</style>
Worked brilliantly!!
