What is HTML?

Before we proceed, it's essential to grasp the concept of HTML and its functionality.

HTML, short for HyperText Markup Language, serves as a markup language used to render web pages. Think of HTML as the framework that forms the core structure of a web page, making it user-friendly and easy to navigate.

For instance, take a look at the web page displayed below, accessible through the following link.

The HTML structure of the aforementioned page is as follows:

index

Now, let's delve into some explanations. Each HTML tag is enclosed within angle brackets, with a left bracket < and a right bracket >. Most HTML tags are designed in pairs, comprising both opening and closing tags. Closing tags are preceded by a forward slash /.

In the schema provided above, we have utilized the following tags:

<html> - defines an html document (compulsory tag for each document);
<title> - defines a page title (displayed in the tab bar);
<body> - defines the document's body;
<h2> - defines the second level of the heading (there are 6 levels available: <h1> - <h6>);
<p> - defines a paragraph.
