text with italics.
Feel free to use <i> element in HTML5. <i> is meant to convey voice,
technical terms, etc.

Italic text nested inside bold text should still be
italic.

The following snippets of text are <em class="{{modifier_class}}">rendered</em> as <i class="{{modifier_class}}">italic text</i>.
Italic text nested inside <b>bold text <i>should</i></b> <strong>still be
<em>italic</em></strong>.
