Markdown Code Block Syntax

Basic and advanced syntaxes for Markdown code blocks including line highlighting.

Basic Syntax

Use triple backticks to create a code block:

```language
your code goes here
```

Example:

function debounce(func, timeout = 300) {
  let timer;
  return (...args) => {
    clearTimeout(timer);
    timer = setTimeout(() => {
      func.apply(this, args);
    }, timeout);
  };
}

Filename

Add :filename.ext after language to show filename label:

```java:GetRowValue.java
private String[] getRowValue(Integer i) {
  // code here
}
```

Line Highlighting and Line Numbers

Add {numbers} to highlight specific lines
Add showLineNumbers to display line numbers

```html:index.html {1,4-6,10} showLineNumbers
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <title>Hello world</title>
  </head>
  <body>
    <h1>Hello world</h1>
  </body>
</html>
```

This will highlight lines 1, 4-6, and 10, while showing line numbers.
