Hi!
If possible, please avoid using private replies unless you’re sharing confidential information such as login credentials: keeping things open makes it a lot easier for other customers in the same boat to make use of threads like this one when researching for problems similar to their own 🙂
This isn’t a line of code I can just add from the edit plugin panel?
Potentially you could edit your theme’s main stylesheet via the Appearance > Editor admin screen and add that snippet at the end or, if your theme has a custom CSS field, that may work too. To set up a tribe-events.css stylesheet though you’d need access to your server’s directory structure – not as daunting as it sounds! – via an FTP client or an online file manager (if your web host provides something like CPanel access, that is).
Does that help?
