## 1.3 Code blocks and snippets

`<pre>` is the default HTML tag for preformatted text.
All code blocks and multi-line snippets should be wrapped in `<pre>{@code ...... }</pre>` at minimum.

Code blocks can be optionally formatted and highlighted using [`highlight.js`](https://highlightjs.org/) with the `<code>` tag.

		// If there are no direct-only or indirect-only blocks, a new block may
		// be inserted after the last require line or block.
		lastRequireIndex = -1

		// If there's only one require line or block, and it's uncommented,
		// we'll move its requirements to the direct-only or indirect-only blocks.
		requireLineOrBlockCount = 0

		// Track the block each requirement belongs to (if any) so we can
		// move them later.
