 The new HTML5 elements we will cover in this article are:

<header>: Used to contain the header content of a site.
<footer>: Contains the footer content of a site.
<nav>: Contains the navigation menu, or other navigation functionality for the page.
<article>: Contains a standalone piece of content that would make sense if syndicated as an RSS item, for example a news item.
<section>: Used to either group different articles into different purposes or subjects, or to define the different sections of a single article.
<aside>: Defines a block of content that is related to the main content around it, but not central to the flow of it.
