.parenthetical class used to keep e.g. "less-than symbol (<)" from wrapping
the end parenthesis onto its own line. Use in a span between the last word and
the parenthetical. So for this example, you'd use
```less-than <span class="parenthetical">symbol (`<`)</span>```

Warnings and notes:

Write the <div>s on their own line. E.g.

<div class="warning">

Warning: This is bad!

</div>
