Sections - Headings

Any single heading element wasn't technically only our "top" list, but collectively (h1,h2,h3,h4,h5,h6), these are important!

Example in JSFiddle

<h1>Primary Heading (1st)</h1>
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit...</p>
<h2>Secondary Heading (2nd)</h2>
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit...</p>
<h3>Tertiary Heading (3rd)</h3>
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit...</p>
<h4>Quarternary Heading (4th)</h4>

<h5>Quinary Heading (5th level)</h5>
