#HTML5

Use HTML5 doctype.
```
  <!DOCTYPE html>
```

It's recommended to use a strict heading hierarchy structure (Single H1), using the legacy (X)HTML document outline approach.

  <!-- Not recommended: HTML5 heading hierarchy --->
  <section>
  	<h1>First header</h1>
  </section>
  <section>
  	<h1>Second header</h1>
  </section>

 	<!-- Recommended: strict heading hierarchy --->
  <section>
  	<h1>First header</h1>
  </section>
  <section>
  	<h2>Second header</h2>
  </section>

Add structure to your content using microdata markup. Use preferred schema.org vocabulary.
Use only those parts of HTML5 that are unobtrusive and have fall backs. See: Feature detection
