Hello, my next two project is a front end social

media site with no data base or backend, hosted on blogger, but is able to enable, chatting, video, user profiles and login details, almost some of the things twitter can do, ( and I know it sounds funny, just for learning ),

How am going to do it is not the problem but if am going to get into trouble doing it is?
Maybe,
