How to determine whether a website is static or dynamic

No, you only see the html- and javascript code sent by the server, you can't see how that is made by the server.

Moreover, this is a question without sense. After all, a site can have more than one page. And some of these can be static and others can be dynamic. So it's not an attribute of a site. It's - at most - an attribute of a page.

I think if a loose sock sticks to the side of the monitor it is "static".

On a serious note, what difference would it make if it were one or the other? That seems to be a more interesting question to me.

An Dynamic website can be described as a form of web site that can be changed even when the code has not been altered. They also alter depending on the browser of the user.

The static web page is a kind of website that's content is fixed, but are only altered when the code altered. In other cases the exact information is provided to each user of the site when they visit the website since the layout and pages are set.

If a webpage has not been changed and shows the same page each time when users enter it, that website is said to be a static website. On the other hand, a dynamic website changes frequently and is shown differently to the users than it was created.
