Syntax

| Italics   | Bold     | Code   |
| --------- | -------- | ------ |
| _italics_ | **bold** | `code` |

Output

Code Blocks

Syntax

we can use 3 backticks ``` in new line and write snippet and close with 3 backticks on new line and to highlight language specific syntax, write one word of language name after first 3 backticks, for eg. html, javascript, css, markdown, typescript, txt, bash

```html
<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>Example HTML5 Document</title>
  </head>
  <body>
    <p>Test</p>
  </body>
</html>
```

Output

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>Example HTML5 Document</title>
  </head>
  <body>
    <p>Test</p>
  </body>
</html>

Expressive Code

Documentation: Expressive Code 🔗

Diff example

```diff lang="js"
  function thisIsJavaScript() {
    // This entire block gets highlighted as JavaScript,
    // and we can still add diff markers to it!
-   console.log('Old code to be removed')
+   console.log('New and shiny code!')
  }
```

Output

function thisIsJavaScript() {
  // This entire block gets highlighted as JavaScript,
  // and we can still add diff markers to it!
  console.log('Old code to be removed')
  console.log('New and shiny code!')
}

Collapsible codeblock

Used Expressive Code Collapsible plugin 🔗

```c collapse
// code/game/q_math.c
float Q_rsqrt( float number )
{
  long i;
  float x2, y;
  const float threehalfs = 1.5F;

  x2 = number * 0.5F;
  y  = number;
  i  = * ( long * ) &y;                       // evil floating point bit level hacking
  i  = 0x5f3759df - ( i >> 1 );               // what the fuck?
  y  = * ( float * ) &i;
  y  = y * ( threehalfs - ( x2 * y * y ) );   // 1st iteration
//  y  = y * ( threehalfs - ( x2 * y * y ) );   // 2nd iteration, this can be removed

  return y;
}
```

Add collapse keyword to force-fold the codeblock.

Output

float Q_rsqrt( float number )
{
  long i;
  float x2, y;
  const float threehalfs = 1.5F;

  x2 = number * 0.5F;
  y  = number;
  i  = * ( long * ) &y;                       // evil floating point bit level hacking
  i  = 0x5f3759df - ( i >> 1 );               // what the fuck?
  y  = * ( float * ) &i;
  y  = y * ( threehalfs - ( x2 * y * y ) );   // 1st iteration
//  y  = y * ( threehalfs - ( x2 * y * y ) );   // 2nd iteration, this can be removed

  return y;
}
