What programing languages are used to make Facebook?

[shortsmoke795]

I want to know what languages are used. My plan is to make a website almost as good as Facebook, or better.

How is Facebook programed?
Is it possible to use future programing languages to make a website better then Facebook?

I know there are a few questions already asked like, this but this one is a little different. I know there is no answer to the question - "Am I going to make a good website", but I might one day.

Does everyone think there will always be new and improved websites like Facebook?

I am a young teenager, so I have a long way to go. I am learning HTML. Could I make a web site as good as Facebook only using HTML and css?
