New Semantic Elements in HTML5
Many sites contain HTML code like:

to show route, header, and footer.
HTML5 offers new semantic components to characterize diverse pieces of a website page:
HTML5 <section> Element
The <section> component characterizes a segment in a document.

Nesting Semantic Elements
In the HTML5 standard, the <article> component characterizes a total, independent square of related elements.
The <section> component is characterized as a square of related elements.
Can we utilize the definitions to choose how to settle components? No, we cannot!
On the Internet, you will discover HTML pages with <section> components containing <article> components, and <article> components containing <sections> elements.
You will likewise discover pages with <section> components containing <section> components, and <article> components containing <article> elements.

Why Semantic HTML5 Elements?
With HTML4, engineers utilized their own most loved ascribe names to style page elements:
header, top, base, footer, menu, route, fundamental, holder, content, article, sidebar, topnav, ...
This made it outlandish for web indexes to distinguish the right site page content.
With HTML5 components like: <header> <footer> <nav> <section> <article>, this will wind up less demanding.
According to the W3C, a Semantic Web:
"Allows information to be shared and reused crosswise over applications, endeavors, and communities."
