print fancybox3 how?

Question

JavaScript

Guys, hello everyone
A pop-up window opens with content using the fancybox3 library. There is a "Print" button in the popup itself.
How can I print a popup window?
It's just that normal methods don't come with print.css, and so on. Since the popup is initially hidden, and the printa window is empty. Please help, maybe I'm doing something wrong.

I found the option, but for some reason something is printed without styles https://jsfiddle.net/alexey10mentor/2mbh8n67/

Answer 1

without styles, because they should also be in the iframe
