Good evening KarenĀ and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
Ideally, I would need specific examples and your site’s URL to make personalized suggestions.
As a first step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?

But, the general idea is to use the class of the body as a starting point in your CSS definitions.
E.g.: .post-type-archive-tribe_events , .tribe-events-page-template, .single-tribe_events
Best regards,
