Web Page DNA

So, what exactly makes up a web page? What does our web browser retrieve from the Internet when we visit an Internet address?

The answer is, files. A web page is just a text file, and inside that text file there are HTML tags, that reference other files on the internet for the browser to retrieve and show as part of the web page.

And nowadays there are many different kinds of files that make up an ordinary web page. It is not uncommon for a web page to be comprised of text, image files, video and sound files, and animation files.

Since a web page is just text, an HTML file does not look any different in our web browser than if we had viewed it in an ordinary text editor, except for the fact that we cannot change the text, because the web browser is meant to view data, not change it.
