Web pages are composed of hyper-text markup (HTML) and linked together over the internet using universal resource locators (URLs), but the "basic unit" of a web page is the tag or HTML element. These tags look like this: some visible content and are the instructions that the web browser uses to format the layout and appearance of the web page.

These tags remain invisible to the person viewing the web page, and only the content that they surround is displayed to the viewer.

Tags are used for different purposes. Some of the purposes include positioning visible content into blocks of lists, to add style to content like italic and bold text, to include a graphic or photo file on the web page, or to link to a different page on the same web site or across the internet.

If you use your browser's view menu you can select "View Source" or "View Page Source" and it will open a window and show you what the web page markup is for that page you are on.

As you can see, there are many different tags and depending on the complexity of the page it can get quite confusing. But underlying the complexity is the basic unit of the tag or HTML element.

This is only a very basic introduction. It's pretty easy to get started building your own simple web page, then it takes time and practice to evolve that skill into more sophisticated designs and layouts.
