Hi there, Mark! Thanks for getting in touch.
Good question. You can customize the layout of your single events by modifying the single-event.php template, which is located at: /plugins/the-events-calendar/views/single-event.php.
I’d also suggest heading over to our Themer’s Guide, which outlines the process for customizing calendar templates without affecting core files. This will help avoid losing your work when a plugin update is available.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
