Is this the correct flow to learn web development?

1. HTML


2. 
   

   CSS

   
   

   i. Media Queries
   
   ii. Bootstrap Framework
   

   
   


3. 
   

   Javascript

   
   

   i. JQuery
   
   ii. AJAX

Also, do I need to learn PHP/Ruby/Phyton if I learned Nodejs? Thanks for your answer.
