A website can be of two types:
  1.  Static Website
  2.  Dynamic Website
Static website 
Static website is the basic type of website that is easy to create. You don't need the knowledge of web programming and database design to create a static website. Its web pages are coded in HTML. 
The codes are fixed for each page so the information contained in the page does not change and it looks like a printed page. 


Dynamic website 
Dynamic website is a collection of dynamic web pages whose content changes dynamically. It accesses content from a database or Content Management System (CMS). Therefore, when you alter or update the content of the database, the content of the website is also altered or updated. 
Dynamic website uses client-side scripting or server-side scripting, or both to generate dynamic content. 
Client-side scripting generates content at the client computer on the basis of user input. The web browser downloads the web page from the server and processes the code within the page to render information to the user. 
In server-side scripting, the software runs on the server and processing is completed in the server then plain pages are sent to the user.
