What Is Markdown?
Markdown is a plain-text formatting syntax designed to be an easy-to-read and easy-to-write way of creating formatted text. Created by John Gruber in 2004, Markdown has since grown to become a ubiquitous tool in the tech industry, particularly among developers.
Originally developed as a writing tool for the web to enable non-programmers to produce web-ready documents without the overhead of HTML, Markdown is now used for all sorts of applications from blogging to documentation and beyond.
Key Features of Markdown:
- Simplicity: No need to remember complex syntax as in HTML or LaTeX.
- Portability: Markdown files can be used in multiple applications without having to modify the syntax.
- Compatibility: Can be easily converted into multiple formats, such as HTML, PDF, etc.
Getting Started with Markdown
Before diving into using Markdown, it’s important to have a basic toolset in place. Although Markdown files typically have the .md
or .markdown
extension, you can create and view them in any text editor, such as VSCode, Sublime Text, or Atom. However, tools like MarkdownPad or Dillinger provide a more tailored experience.
Basic Markdown Syntax
Headers
To create a header, use the #
symbol followed by a space. The number of #
symbols represents the header level, with one #
for level one headers, two ##
for level two, and so forth.
# Header 1
## Header 2
### Header 3
Code language: PHP (php)
Emphasis
Use asterisks (*
) or underscores (_
) to emphasize text:
- Italic: Enclose the text in single asterisks (
*italic*
) or underscores (_italic_
). - Bold: Enclose the text in double asterisks (
**bold**
) or underscores (__bold__
).
Lists
- Unordered lists: Use dashes (
-
) or asterisks (*
).
- Item 1
- Item 2
- Subitem 2.1
Code language: CSS (css)
- Ordered lists: Use numbers followed by periods.
1. First item
2. Second item
1. Subitem 2.1
Code language: CSS (css)
Links
The basic syntax for a link is [link text](URL)
. For example:

Images
Images use a similar syntax to links, but with an exclamation point preceding it: ![alt text](image URL)
.

Code Blocks
For inline code, wrap your code with backticks: `code`
.
To create code blocks, use three backticks (“) or indent lines with four spaces:
""" Code Block """
Code language: JSON / JSON with Comments (json)
Best Practices When Writing Markdown
While using Markdown is fairly straightforward, adhering to best practices can make your Markdown documents more effective and readable:
- Consistent Style: Choose either asterisks or underscores for emphasis and maintain that style throughout.
- Limit Line Length: Try to keep your lines under 80 characters to reduce horizontal scrolling and enhance readability.
- Descriptive Links and Images: Use meaningful descriptions for links and alt text for images to improve accessibility and SEO.
Markdown Extensions
Numerous extensions have been developed to extend Markdown’s capability. Some popular ones include:
- GFM (GitHub Flavored Markdown): Adds features like tables and checkboxes.
- MathJax: For rendering mathematical notation.
