Thank you Michael!
I’m fairly new to WordPress and I wasn’t certain what for, or where to look..! I feel like I’m close; I’m using the Heroic Knowledge Base theme so I think the file directing the way the categories look is hkb.taxonomy.category.php. I see that what I did, according to the link you referred me to, works when using the code below! But it changes all my categories, and not only my desired one…
<div class="hkb-category__header">
<h2 class="hkb-category__glossary">
</h2>
<?php the_content(); ?>
</div>
How would I only affect one category?
