Hey there,
Thanks for reaching out!
Our themer’s guide has some great info on customizing our plugins, including our page templates. The template page for our events page is the same, it just calls in different views. You can find these in wp-content/plugins/the-events-calendar/src/views/ (for the Events Calendar views – default-template.php is the base template) and wp-content/plugins/events-calendar-pro/src/views/pro for the views that come with Pro.
In order to make changes to only the category page, I would recommend taking a look at tribe_is_event_category and some of our other functions. To change the views for category pages, this post has a snippet that will help you do that.
Let me know if you need any help with any of this or have any questions!
Thanks,
Jennifer
