HTML -> HyperText Markup Language

Tags in HTML

Tag is a basic formatting tool in HTML that helps in giving proper structuring to a page. there are numerous tag predefines that have their own meaning and purpose in the structuring. four basic HTML tags required for the proper functioning of an HTML code are:

• html -> Used to represent the root of the html document
• title -> Defines the title of the project/document, and also shown in the browsers title bar
• head -> This acts as a container to hold all the metadata for the project, it is placed before the body tag
• body -> This defines the body of the document, contains all the contents of an HTML document. Only one body tag is allowed in an HTML document.

What is Semantic HTML and why should we use it?

Semantic HTML elements are those that express their meaning in a way that is both human and machine-understandable, it also describes the meaning of the web page rather than a presentation. By adding meaningful tags the page provides additional information about the document which helps in an improved communication to viewers. It also aids the search engine to deliver a proper response page for a query/search. semantic HTML tags also improve the presentation of the page also, particular format/style is attached with each tag which helps in conveying the message in an intended manner.
