Markdown Advanced Techniques

Supported HTML Elements

Tags that are not covered within the scope of Markdown can be directly written in the document using HTML.

Currently supported HTML elements include: <kbd> <b> <i> <em> <sup> <sub> <br>, etc., for example:

Use <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>Del</kbd> to restart the computer

Escaping

Markdown uses many special symbols to represent specific meanings. If you need to display these symbols, you need to use escape characters. Markdown uses a backslash to escape special characters:

**Bold text** 
\*\* Normal display of asterisks \*\*

The output is:

Markdown supports the following symbols preceded by a backslash to help insert ordinary symbols:

\   Backslash
`   Backtick
*   Asterisk
_   Underscore
{}  Curly braces
[]  Square brackets
()  Parentheses
#   Hash mark
+   Plus sign
-   Minus sign (hyphen)
.   Dot
!   Exclamation mark

Formulas

Markdown Preview Enhanced uses KaTeX or MathJax to render mathematical expressions.

KaTeX has faster performance than MathJax but lacks many features that MathJax has. You can check KaTeX supported functions/symbols to see what symbols and functions KaTeX supports.

Default delimiters:

• Mathematical expressions within $...$ or \(...\) will be displayed inline.
• Mathematical expressions within $$...$$ or \[...\] or ```math` will be displayed in a block.

  $$
  \begin{Bmatrix}
     a & b \\
     c & d
  \end{Bmatrix}
  $$
  $$
  \begin{CD}
     A @>a>> B \\
  @VbVV @AAcA \\
     C @= D
  \end{CD}
  $$
  

The output is:
