Hi, Joanna 🙂
Welcome to the premium support forums and thank you for reaching out! While theme customizations typically extend beyond what we’re able to cover here, I’ll do my best to provide helpful assistance. Have you tried different options found under Events > Settings > Display? Another useful tip is using your ‘Inspect’ tool as shown in this YouTube Video.
Our New User Primer does a great job of breaking down how our plugin handles styles, from “grabbing” theme from your theme (Full Style) to giving you a nearly blank slate (Skeleton Style).
I hope this helps and please keep me updated with your progress. Thanks again and have a great evening. Cheers!
