Before we move on, we need to understand what `html` is and how it works.

`HTML` or `HyperText Markup Language` is a markup language used for displaying web pages. `HTML` forms a 'skeleton' of a web page, so it's convenient to navigate.

For example, look at the web page below. You can navigate to it using the following <a href = 'https://codefinity-content-media.s3.eu-west-1.amazonaws.com/35fdd0a9-2b4b-4032-9ac4-3d848aa08650/test_page.html' target = '_blank'>link</a>.

The `html` structure of the page above is the following.
```html
<html>
    <title>
        Test page
    </title>
    <body>
        <h2>What is HTML?</h2>
        <p>HTML, or HyperText Markup Language is markup language used for displaying web pages.</p>
    </body>
</html>  
```    

Now to explanations. Each **html tag** is enclosed by the left `<` and right angle brackets `>`. Most of the html tags come in pairs - **opening** and **closing tags**. Closing tags are preceded by a backslash `/`.

In the schema above, we used the next 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**.

Here we will explore the structure of the HTML file,  how to load it, and work with the data in the file.
