How GOOGLE is created using HTML?

Answer 2

Google is not only html/css, it is way more than that. Google is :
- GSearch => search engine
- GSuite => the Google account and all Google services linked to it
- YT
It uses databases, powerful search algorithms, AI, and many other things. So I bet they use at least 5 / 6 languages (including their own language : Go).
