Wraps a string with a given HTML tag. Has the nice benefit of returning null if there is no data, eliminating the need for simple {{ if }}
wrappers.
title: As the World Turns
{{ title | wrap('h1') }}
<h1>As the World Turns</h1>
You may also use Emmet-style CSS classes to be added to the tag.
{{ title | wrap('h1.fast.furious') }}
<h1 class="fast furious">As the World Turns</h1>
