## HTML
**Hyper Text Markup Language (HTML)** is a markup language for web documents, defines rules for structuring text, adding images, creating tables, forms, and lists. An HTML document is a text file with a .html extension and is interpreted by web browsers to display a web page, not the source code with markup elements.

## Tag
**Tag**  is the fundamental element. It is the basic unit that forms any web page, indicating an item such as a heading, list, text paragraph, or image.
To differentiate tags from regular text in a document, angle brackets are used. Tag name and attributes are put inside of the `<>`.

``` html
<tag_name>...</tag_name>
```

The opening tag denotes the beginning of an element, and the closing tag denotes its end. To create a closing tag, add a slash (`/`) before the tag name. The content is contained between the opening and closing tags.

To make an explanation or leave a note in the source code **comments** are used.
