A static website consists of a maximum of 3 elements. These 3 elements are :
1.Html file
2.Css file
3. and .js file but the last two are not necessary.
The “pre-written” code (the combination of 3 previous files) is always the same for every user unless the website owner makes a change. The actions or preferences of the user can’t affect the initial code.
Since static Web pages contain fixed code, the content of each page does not change unless it is manually updated by the webmaster. This works well for small websites. Static sites that contain a lot of pages are often designed using templates. This makes it possible to update several pages at once, and also helps provide a consistent layout throughout the site.
For example, where will be the images placed or the distance between paragraphs.
If the server stores a static website it will send that code once. For instance, the online visitor can’t create an account and send that details back to the server. He can’t generate content such as comments. A static site isn’t connected with a database in the server so there is no place to store all that data and retrieve it when needed.
The best thing of this static website is that sincce the files that contain code are more minimalistic in a static website, you need less storage and less bandwidth to use. So, even if you get a lot of traffic you will need not need the same resources such as a dynamic website. That means you will pay less, especially for a successful site. Static website examples :
1.Reactjs.org The React Javascript Library Website
2.braun.com/ The braun brand site
3.tagaholic.me/ a simple blog

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.
Suppose …
The server creates a different interface based on the user’s inputs. In that case, the look of the site depends on the username and password of the person. The Facebook site has stored the details of the user in a database along with other details such as interests, facebook friends, liked pages, etc. So it will return an interface adjusted on the user’s history and general information.
So A dynamic website needs a database to function. Best thing of this dynamic website is that even a person without coding knowledge can use a cms such as WordPress to create pages and posts for his site.
Dynamic website examples :
1.twitter,
2.pinterest,
3.mails.
