Just as a tree has roots, a trunk, and branches, a webpage needs a solid structure.
This page uses Semantic HTML. This means the tags describing the content
actually tell the browser (and screen readers) what the content is.
The Article Tag
I am wrapping this text in an <article> tag.
This signifies that this block of content is independent and self-contained—like
a specific species entry in a field guide.
The Code Behind This
If you view the source of this page, you won't just see a bunch of
<div> tags. You will see specific landmarks that define
the layout clearly.
