Hi giovalt,
We apologize for the late response. Yes, for your solution please go to ‘Theme Directory > template-parts > content.php’. On line no: 33, you will find below line of code.
<div class="post-img" style="background-image: url('<?php echo esc_url(get_the_post_thumbnail_url(get_the_ID(),'full')); ?>');"></div>
please replace the mention code with the below Custom Code:
<img src="<?php echo esc_url(get_the_post_thumbnail_url(get_the_ID(),'full')); ?>" class="img-fluid" alt="">
after that please go to the ‘Dashboard > Appearance > Customize > Additional CSS’ and paste the below Custom CSS code.
.page-single-img-wrap {
background: none;
}
.page-single-img-wrap:before {
display: none;
}
.page-single-img-wrap img {
width: 100%;
}
NOTE: Please make sure you make the child theme first before customizing the Theme code so that your customized code won’t get lost when updating the Theme to a newer version in the future.
Thanks
