Markdown: Text Formatting with Square Brackets

Autore: Francesco Zinghinì | Data: 28 Febbraio 2026

Markdown is a lightweight markup language that is gaining increasing popularity among writers, bloggers, and developers. Why markdown text formatting? Simply because it allows you to format text in a simple and intuitive way, without having to resort to complex HTML tags. In this article, we will discover what Markdown is, how it is used, and how it can improve your content’s SEO. We will learn, in particular, how to use square brackets to create links and insert footnotes.

Markdown Basics

Markdown is based on a simple and readable syntax, which uses common characters like asterisks, hash signs, and square brackets to format text. Here are some basic elements:

  • Headers: created with the symbol #, followed by a space and the header text. The number of hash signs indicates the header level (from H1 to H6).
  • Paragraphs: created simply by hitting enter twice.
  • Bulleted lists: created with *, +, or -, followed by a space and the item text.
  • Numbered lists: created with a number followed by a period and a space.
  • Bold: obtained by enclosing the text between two asterisks **text** or two underscores __text__.
  • Italics: obtained by enclosing the text between one asterisk *text* or one underscore _text_.
  • Strikethrough: obtained by enclosing the text between two tildes ~~text~~.

Example:

Markdown

# This is an H1 header
## This is an H2 header

This is a paragraph of text.

*  Item 1
*  Item 2

1. First element
2. Second element

**This text is bold.**

*This text is italic.*

~~This text is strikethrough.~~

Square brackets are one of the key elements of Markdown. To create a link, just follow this simple syntax:

[link text](URL)

Example:

Markdown

[TuttoSemplice.com](https://www.tuttosemplice.com)

This code will generate the following link: TuttoSemplice.com

Advanced Formatting with Markdown

In addition to basic elements, Markdown offers several options for more advanced formatting:

  • Tables: created using pipes | to separate columns and hyphens - to define the header.
  • Images: inserted with the syntax ![alt text](image URL).
  • Source code: formatted by enclosing it between backticks `code` or three backticks for code blocks.
  • Footnotes: created with the syntax [^note] and defined at the bottom of the document with [^note]: note text.

Using square brackets for footnotes

Here is how to insert a footnote with Markdown:

Markdown

This text contains a footnote.[^1]

[^1]: This is the footnote.
