# Inline code & code block

The Advanced WYSIWYG editor supports two ways to display code in your articles: inline code and code blocks.

- **Inline code** formats a short snippet or command within a line of text, distinguishing it visually from the surrounding prose.
- **Code block** displays a multi-line block of code as a separate section with syntax highlighting, a language label, and a copy option.

Document360 uses [Prism.js](https://prismjs.com/) for syntax highlighting and supports a wide range of programming languages in code blocks.

## Recommended scenarios

- Use inline code to reference a variable name, file path, command, or parameter within a sentence — for example, "Set the value of `max_retries` to 3"
- Use a code block for multi-line scripts, API request examples, configuration files, or any code readers may need to copy and run
- Use a custom language label when documenting a proprietary scripting language or configuration format not available in the default list
- Use code blocks inside tab elements to show the same API call in multiple languages side by side — for example, Python, JavaScript, and cURL in separate tabs

## Inline Code

Inline code is applied directly to selected text within a paragraph without creating a new block.

1. Select the text you want to format as inline code.
2. In the floating toolbar, click the **Inline code** icon or use the keyboard shortcut `Ctrl + E`.

The selected text appears styled as code within the sentence.

## Code Block

A code block creates a dedicated section for displaying multi-line code with syntax highlighting.

To insert a code block, use any of the following methods:

1. Click the **Code block** icon in the Quick insert menu (appears when a block is empty)
2. Type three backticks ````` and press `Enter`
3. Use the slash command `/code block` and press `Enter`

After inserting a code block:

1. Click on the code block — a floating menu appears.
2. Select the desired language from the dropdown for syntax highlighting.
3. Enter your code inside the block.

To copy the block, click the **Copy** icon. To remove it, click the **Delete** icon.

**Setting a custom language label:** If the language you need is not in the list, select **Custom** from the dropdown, click the **Edit** icon, enter your desired title, and click **Update**.

  NOTE

In the Advanced WYSIWYG editor, a code block always requires a heading. To hide the heading on the knowledge base site, apply Custom CSS via **Settings** > **Knowledge base site** > **Custom CSS & JavaScript.** This will hide the heading across all code blocks on the site. If you prefer code blocks without a heading, use the Markdown editor instead.

## Best practices

- Use inline code for short references (one line or less) and code blocks for anything longer
- Always select the correct language for your code block — accurate syntax highlighting improves readability and signals the correct language to readers
- Add a descriptive heading to your code block so readers know what the code does before reading it
- Keep code blocks focused — one block per distinct snippet or example; avoid combining unrelated code in a single block
- Keep code clean and free of placeholder comments that could cause errors if run directly
