HTML5 hgroup Element
hgroup element is used to semantically group a headline and subheadline into
the same header group.
Look at this example title:
<h1>Wealth</h1> <h2>How the rich get richer, and how you can get richer too.</h2>
h2 headline is actually part of the same title, but a browser or
web crawler cannot see that. To signal that you enclose the two elements in a
element, like this:
<hgroup> <h1>Wealth</h1> <h2>How the rich get richer, and how you can get richer too.</h2> </hgroup>
h2 elements are grouped into a single semantic headline.
A web crawler will now understand that these two elements are part of the same headline.
