Hi Ellen,
Thanks for reaching out! If you’re looking to edit any of the default templates that are used by our plugins, our Themer’s Guide should have all the info you need to get started! You’ll find that guide on our Knowledgebase here:
https://theeventscalendar.com/knowledgebase/themers-guide/
I hope that helps! If you should have any other questions, please don’t hesitate to log into your TheEventsCalendar.com account and submit a new post to our Events Calendar PRO forum. While we’re not able to provide in-depth assistance with customizations, we’re happy to try and point users in the right direction where we can. Don’t hesitate to pay us a visit! 🙂
Cheers, and happy customizing!
