To preserve the wrapping inside code blocks, horizontal scrolling is implemented. To make sure scrolling is keyboard accessible, code blocks are focusable. An `aria-label` is provided to identify the code block to screen reader users. To preserve the wrapping inside code blocks, horizontal scrolling is implemented.

## Annotated HTML
Since the structure of HTML is critical to interoperable web interfaces, **Infusion** offers the ability to highlight and annotate specific HTML elements and attributes using the `html` shortcode.
Take an accessible dialog. You may wish to point out key attributes that make that dialog support assistive technologies:
{{<html>}}
<div ((role="dialog")) ((aria-labelledby="dialog-heading"))>
<button ((aria-label="close"))>x</button>
<h2 ((id="dialog-heading"))>Confirmation</h2>
<p>Press <strong>Okay</strong> to confirm or <strong>Cancel</strong></p>
<button>Okay</button>
<button>Cancel</button>
</div>
{{</html>}}
You mark out the highlighted areas with double parentheses like so:
{{<codeBlock>}}
&#x7b;{&lt;html>}}
&lt;div ((role="dialog")) ((aria-labelledby="dialog-heading"))>
&lt;button ((aria-label="close"))>x&lt;/button>
&lt;h2 ((id="dialog-heading"))>Confirmation&lt;/h2>
&lt;p>Press <strong>Okay</strong> to confirm or <strong>Cancel</strong>&lt;/p>
&lt;button>Okay&lt;/button>
&lt;button>Cancel&lt;/button>
&lt;/div>
&#x7b;{&lt;/html>}}
{{</codeBlock>}}
Better still, if you include `numbered="true"`, each highlight is enumberated so you can reference it directly in the ensuing text.
{{<html numbered="true">}}
<div ((role="dialog")) ((aria-labelledby="dialog-heading"))>
<button ((aria-label="close"))>x</button>
<h2 ((id="dialog-heading"))>Confirmation</h2>
<p>Press <strong>Okay</strong> to confirm or <strong>Cancel</strong></p>
<button>Okay</button>
<button>Cancel</button>
</div>
{{</html>}}
You just include `numbered="true"` on the opening shortcode tag:
{{<codeBlock>}}
&#x7b;{&lt;html numbered="true">}}
&lt;div ((role="dialog")) ((aria-labelledby="dialog-heading"))>
&lt;button ((aria-label="close"))>x&lt;/button>
&lt;h2 ((id="dialog-heading"))>Confirmation&lt;/h2>
&lt;p>Press <strong>Okay</strong> to confirm or <strong>Cancel</strong>&lt;/p>
&lt;button>Okay&lt;/button>
&lt;button>Cancel&lt;/button>
&lt;/div>
&#x7b;{&lt;/html>}}
{{</codeBlock>}}
