Single page/html file cef or more pages/html files?

[Skole]

Hello, I have a question to ask. 

What is difference between one html page for every ui and mulitple html files in cef. I hope you understand me.

Let's say I'm making login system, now should I make login.html for that ui and then make selection.html for character selecetion and so on...

Or should I use something like React for my cef and put all in html file and use something like Redux for state managment?

Is there difference in performance, what is faster? And what would you choose?
