Good evening Brandon and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the struggle you experienced.
I would love to help you with this topic.
You are 100% right, we can totally improve on documentation and we will.
With that in mind, there is actually no need to put full CSS files in your /tribe-events/ folder (unless you have a reason to).
You can simply add rules to your child theme’s style.css file.
You are welcome back in our support forums any time 🙂
For now, I am going to close this thread.
Have a great week!
Geoff B.
