Markdown

This text talks about the basic syntax of Markdown.

INTRODUCTION

Markdown is one of the most popular languages for making notes and the markdown file usually end up with .md.

TITLES

Markdown use # to represent titles.

The line above ================ (equals #) or ----------------- (equals ##) is also title.

TABLE OF CONTENTS

Markdown can generate Contents automatically by[TOC]or[toc] token based on you titles after # token.

Note: You have to add a blank line after the [TOC] token, and click the Preference > Rendering > Detect table of contents token choice in MacDown app.

SYMBOLS

Inline Formating

1. *Italy* is Italy.
2. **Bold** is Bold.
3. ***Italy and Bold*** is Italy and Bold.
4. ~~delete~~ is delete.
5. `inline code` is inline code.

6. >quote is

   quote

7. *********,_______ or ---------- will be a line, like ****

Lists

1. Ordered list.

   1. First.
   2. Second.
   3. Third.

2. Unordered list

   • First.
     • Color.
       • Black.
       • Yellow.
     • Size.
   • Second.

Note: There is a blank space behind the List symbol *, + and -.

Mathematics

Markdown supports LATEX math expressions with Internet connection. We usually use symbol $ like $\int_0^\infty f(x)\mathrm{d}x$, then we will get

\(\int_0^\infty f(x)\mathrm{d}x\) .

Code Blocks

As we know, Markdown always quotes code blocks, we can add tab in the front of every line to declare that this part is a code block. Or we can use ` ` ` to bracket the code block and add the language name behind the first ` ` `(Note:there is a space blank between the first ` ` ` and specific language name).

#include <iostream>
#define Pi 3.1415926
using namespace std;
int main()
{
	cout << "Hello, world!" << endl;
	return 0;
}

or

import numpy as np
print('Hellow, world!')

if the code language is not specific, we can just ignore it or we can use tab:

import numpy as np
print('Hellow, world!')

Comments

<!--COMMENTS--> is the expression used in HTML, so it is not recommended in Markdown.

Hypertext

1. [Name](address "capital") is Physics Review Letter.

   Note: “captital” is the text shown when you put your mouse cursor on the hypertext.

2. We can put all the hypertext in order and cite them with only names and their serial numbers. The specific address will be listed in order at the end of the text.

   eg:

   The most famous physcial journals like [Physics Review Letter][1] and [Physics Review B][2], etc.

   [1]:https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.109.096603 “Shufeng Zhang”

   [2]:https://journals.aps.org/prb/abstract/10.1103/PhysRevB.71.184426 “Jianwei Zhang”

   then we will get:

   The most famous physcial journals like Physics Review Letter and Physics Review B, etc.

1. We can also just use the <> to represent hyper address, like <https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.109.096603>

   We can see the paper in https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.109.096603 .
