Where to learn the intricacies of positioning elements using css?

Question

css

Good day to all!
Lately, I’ve come across the fact that I don’t fully understand the positioning of elements using css, only if the task does not involve the use of flex (everything is very clear with them).
Actually, a question! Do you know any resources where you can learn the intricacies of css positioning?
Thanks in advance for your reply.
