The <nav> HTML element is used to define a section of a webpage that contains navigation links. It is a semantic element introduced in HTML5 to help identify the primary navigation areas within a document, such as menus, tables of contents, or any other group of navigational links. The <nav> element enhances the accessibility and structure of a webpage by clearly delineating navigation sections.
Usage and Characteristics

It can be used multiple times on a page if there are different navigation sections, such as a main site navigation and a secondary navigation for a specific section. Here is an example of how the <nav> tag can be used:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
