With the CodeBlock extension you can add fenced code blocks to your documents. It’ll wrap the code in `<pre>` and `<code>` HTML tags.

Type <code>&grave;&grave;&grave;&nbsp;</code> (three backticks and a space) or <code>&Tilde;&Tilde;&Tilde;&nbsp;</code> (three tildes and a space) and a code block is instantly added for you. You can even specify the language, try writing <code>&grave;&grave;&grave;css&nbsp;</code>. That should add a `language-css` class to the `<code>`-tag.

::: warning No syntax highlighting
The CodeBlock extension doesn’t come with styling and has no syntax highlighting built-in. Try the [CodeBlockLowlight](/api/nodes/code-block-lowlight) extension if you’re looking for code blocks with syntax highlighting.
