Semantic HTML

Web design nowadays is not just about displaying content on a page its about creating experiences understood both by humans and machines and thats where Semantic HTML comes into picture.

Semantic HTML - It refers to the usage of HTML elements that convey meaning beyond just presentations.

Think of it as labels that make it easier for understanding. For instance ,picture yourself entering into a company building and the doors are not labelled. You will really have a hard time finding a specific room i.e the accountants office whereas if the rooms are labelled ,it becomes easier for someone to know where they are going.

Examples of Semantic HTML includes:

header – represents the introductory content of a page.
nav – defines a section of navigation links.
main – identifies the main content of a page.
article – represents an independent piece of content.
footer – represents footer information about its nearest section or page.
