Getting Started: The Basic Syntax
Headings
ATX-style headers use one to six hash characters (#) at the beginning of the line, corresponding to <h1> through <h6>.
Syntax:
# This is an H1
## This is an H2
### This is an H3
#### This is an H4
##### This is an H5
###### This is an H6
Paragraphs and Line Breaks
Paragraphs are created by simply writing lines of text separated by one or more blank lines. To force a line break within a paragraph, end a line with two or more spaces.
Syntax:
This is the first line of a paragraph.
This is the second line of the same paragraph.
This is a new paragraph.
This line will break
into a new line.
Emphasis: Bold and Italic
Markdown uses asterisks (*) and underscores (_) to indicate emphasis. Single asterisks or underscores create italic text, while double asterisks or underscores create bold text.
Syntax:
*This text will be italic.*
_This text will also be italic._
**This text will be bold.**
__This text will also be bold.__
***This text will be bold and italic.***
___This text will also be bold and italic.___
Blockquotes
Blockquotes are created by preceding lines with a greater-than sign (>).
Syntax:
> This is a blockquote.
> It can span multiple lines.
> > Nested blockquotes are also possible.
> Back to the first level.
Lists: Ordered and Unordered
Markdown supports both ordered (numbered) and unordered (bulleted) lists.
Syntax:
* Item 1
* Item 2
+ Nested Item 2.1
- Nested Item 2.2
1. First item
2. Second item
3. Third item
Links
Markdown supports two styles of links: inline and reference.
Syntax:
This is [an example](http://example.com/ "Optional Title") inline link.
This is [an example][id] reference-style link.
[id]: http://example.com/ "Optional Title"
Images
Markdown’s image syntax is similar to its link syntax, with the addition of an exclamation mark (!) at the beginning.
Syntax:
![Alt text][id]
[id]: /path/to/image.jpg "Optional Title"
Code: Inline and Blocks
Code spans are used for inline code snippets, created by wrapping text with single backticks (`). Code blocks are for longer snippets and are created by indenting lines with four spaces or by using fenced code blocks.
Syntax:
Use the `printf()` function.
This is a code block.
It preserves whitespace and line breaks.
Horizontal Rules
Horizontal rules are used to visually separate content. You can create them by placing three or more hyphens (-), asterisks (*), or underscores (_) on a line by themselves.
Syntax:
* * *
---
*****

Tables
Tables are created by using hyphens (-) to separate the header from the body, and pipes (|) to separate columns. You can specify column alignment by adding colons (:).
Syntax:
| Left-aligned | Center-aligned | Right-aligned |
| :----------- | :------------: | ------------: |
| Content | Content | Content |
| More Content | More Content | More Content |
Fenced Code Blocks with Syntax Highlighting
Fenced code blocks are created by wrapping your code in triple backticks (```) or triple tildes (~~~). You can enable syntax highlighting by adding a language identifier after the opening fence.
Syntax:
```python
def greet(name):
print(f"Hello, {name}!")
```
Task Lists
Task lists are a great way to create checklists in your Markdown files. They are supported by GitHub Flavored Markdown and other variants.
Syntax:
- [x] This is a completed task.
- [ ] This is an incomplete task.
Strikethrough
Strikethrough text is created by wrapping text with two tildes (~~).
Syntax:
~~This text will be struck through.~~
Emoji
Many Markdown processors support emoji shortcodes. For example, typing :smile: will render as 😄.
Syntax:
I love Markdown! :heart:
